The life of Garibaldi Essay Get the clamp ready and place the tile on the clamp, then place the conical flask on the tile. Rinse your burette with your diluted HCl to replace any previous liquids which may intervene in the results. Now secure the burette to the clamp making sure the nozzle is facing in the conical flask. You should now have your apparatus set-up like this: 30/5230/35230/image006. gif Funnel Burette filled with diluted HCl Conical Flask Clamp Tile Ca(OH) and Indicator i Now everything should be ready. From your volumetric flask, empty out the diluted HCl into a normal beaker. Using this beaker fill the burette up to the 0 mark with a funnel. i Start titrating slowly until the solution has totally reacted. Then record the results noting how much HCl you used. Record the results in a suitable format and repeat the experiment at least three more time for more accuracy. Finally record the average (mean) titre. i SAFTEY: this is extremely important as you are handling hydrochloric acid. Goggles must be worn at all times, hair must be tied back and bags must remain under the desk. If anything goes wrong, consult the teacher immediately. Always remember to work safely as HCl can be hazardous to your skin, the indicator may stain your clothing as well. (Accuracy): The pipette, burette and volumetric flask only have a percentage error of + or 0. 1%. This is a small error. That is why they are used in this experiment. Be sure to take precautions such as making sure that when you pour in the HCl or Ca(OH) you do not let it run down the sides because some will be left on the sides thus making an inaccuracy. As you can see above, the bold says10. 0cm3 of your Ca(OH), when instead it should have been 25. 0cm3. The reason for this is because there was not enough of the Ca(OH) to perform all the experiments. This is a limitation due to the fact that 25. 0cm3 would have been a more accurate measure because 10. 0cm3 may not be enough for a clear result.

In this part of the investigation I aim to determine the final concentration of the limewater solution. I will go through my calculation step by step and explain what I am doing along the way. Starting off, lets look at what we have. The equation for the reaction is: 30/5230/35230/image001. gif Ca(OH)2(aq) + 2HCl(aq) CaCl(aq) + 2H2O(L). For the Ca(OH) we are trying to find the concentration in mol g dm-3. However we have the volume (10. 0cm3 is how much we er solution. This would change the colour of the solution to light orange which would change to pink by the end of the titration. 5. After that I will place the flask onto a white tile placed on a clamp stand. Then I will open the tap of the burette that is held in the clamp stand and let the acid neutralise the alkali. 6. By the end of titration the limewater solution turns pink which indicates that it has been neutralised. 7. I will repeat the experiment at least thrice to make it a fair test. Repeating the experiment will also ensure that the results that I get are accurate. The reaction that takes place can be described with the help of this balanced equation: Ca (OH)2 + 2HCl i CaCl2 + 2H2O In order to get reliable results from the exper at the end point would be reached before the equivalence. Variable Control You need t ensure that you take your chemicals from the same batch so as not to get two different concentrations each time you test them. Temperature and pressure should have no effect on the reaction Organisation Set up the equipment as shown in the diagram below, ensuring that the burette valve is closed. Run de-ionised water through the burette and wash all of the equipment with it First of all dilute the hydrochloric acid using by adding slowly 25ml of 2.00moldm-3 HCl to 475ml of de-ionised water in the 500ml beaker. Then, using a pipette, put 100ml of the HCl solution into the burette Put 50ml of limewater into a conical flask using the pipette then add 5 drops of methyl orange to the solution, this should turn the solution a pale orange Open the .. . molarity 1dm3 = 10x10x10cm3 = 1000cm3 1(Molarmass) = 8. 12gdm3 Evaluation My practical experiment went quite well and I got a variety of results, which were suitable for the task given. My results show that I got two identical results and one just 1. 1cm3 off. Which suggests that I have been accurate and precise during the experiment. By being accurate it came about by specific apparatus I used, which restricted errors. However during the experiment I came across an array o

Whitman and Neruda as Grassroots Poets Essay -- Poet Poetry Poem Paper

Whitman and Neruda as Grassroots Poets â€Å"The familial bond between the two poets [Walt Whitman and Pablo Neruda] points not only to a much-needed reckoning of the affinity between the two hemispheres, but to a deeper need to establish a basis for an American identity: ‘roots,’ as Neruda referred to his fundamental link with Whitman† (Nolan 33). Both Walt Whitman and Pablo Neruda have been referred to as poets of the people, although it is argued that Neruda with his city and country house, his extensive travels, and his political connections, was never really â€Å"one† of the mass. Nonetheless, his work and energies went into supporting the common working man, and not the elite. By the late 1940’s Neruda had openly defined himself as a communist, looking for the equal treatment of all citizens of Peru. Whitman, though not overtly political like Neruda, did emphasize the equality between all in his writing. The appellation, â€Å"poet of the people,† is used to indicate their sympathies towards a commonality in humans, if not the â€Å"common man†. As the term â€Å"commoner† carries various connotations and needs much explaining, I prefer to discuss the two authors as grassroots poets. â€Å"Poets of the people† and â€Å"grassroots poets† have many similarities, but b y using the term grassroots I draw on grassroots theater studies which illuminate certain artistic purposes and themes. Thinking of Whitman and Neruda as grassroots poets can deepen our understanding of their personas and their work, and especially indicate a similarity of purpose between the two poets who employed different structural styles of writing. First and foremost, the term â€Å"grassroots† hinges on a sense of community. It implies a political motivation from the bo... ...nity theatre is to create a dialectic between the present state and future possibilities of particular communities, moderated by a knowledge of, and an identification with, those communities† (Kershaw, 61). With this basic understanding of â€Å"grassroots† with in the context of community theater, let us proceed to a comparative study of grassroots sentiments in excerpts from Neruda’s The Heights of Macchu Picchu, and Walt Whitman’s Song of Myself.

Revolutionary Mothers Essay

Carol Berkin masterfully presents a glimpse of the lives of the women who were affected by the Revolutionary War through many different eyes, views, and opinions in Revolutionary Mothers: Women in the Struggle for Independence. She paints a vivid picture in your mind of how the war affected these women by not focusing on one race or political view, but rather through multiple races and political views. Throughout this book, the author describes the women of the Revolution as courageous, yet intelligent, strong, yet resourceful. In Berkin’s writings, her admiration for these women is apparent. She describes how these women felt as if they new that they had very important roles in the war, however they didn’t see them as much more than supporting the men who actually were meant to run the country. As strong willed as many of these women were, they made weak attempts at equal rights during these male dominated times. This book was given validity through supporting texts. Berkin used other authors such as Elizabeth Ellet to drive her points home. She is able to give even more personal insight from letter correspondences as well as diaries from women who were caught up in the midst of these times. Finally, Berkin uses documents such as the Philipsburg Proclamation, the Edenton Resolves, and the Book of Negroes as a foundation to much of the support or neglect thereof for the Americans. I believe that the author did an outstanding job of presenting the information in this book. Many authors would have tried to intertwine these women’s stories in order to make the story more interesting as a whole. Instead she sets aside a chapter to different groups she wants to go into detail discussing. For instance, she doesn’t try to compare and contrast the women who were on the home front to the women who followed the armies. Instead, she helps you realize the importance of both by devoting time to each group. This allows us to learn more about these women and get a grasp of what they really went through. The multiple number of resources Berkin used keep this book interesting. She does a good job of making sure there are notes in the back to go along with each chapter in the case that you want to, or need to, learn more about the chapter or to receive expanded content. Also, these notes give you a great resource for continuing your research on that chapters topic. I consider myself somewhat of a history buff. I had learned much about the wars and causes of the Revolutionary War. I had seen many documentaries about the war. This book however lent it’s hand to a completely different side of the war. You never learn about the women who are left at home, nor the women who follow the armies, nor the women who were acting as spies. My knowledge has been impacted greatly by this book. My eyes have been opened to a whole new side of the war that you never even knew existed. Overall I believe this book was a great, and relevant book for this course. I think it was interesting as a whole because of the extensive resources Berkin used. I will admit that there were some dry parts that I had to work my way through, but the knowledge gained was worth the fighting through.
