== 5/13/05 ==<br> -Copper(II) sulfate CuSO<sub>4</sub>*5H20.<br> -I made a 0.10M solution of copper(II) sulfate. To do this I found the molar mass of copper(II) sulfate. Then i was able to find the number of moles needed in the solution with the molarity and the volume. With the moles and the molar mass I could find the exact grams needed to make a 0.10M solution. I then measures out the solid copper(II) sufate and dissolved it the the DI water.<br> [[Copper(II) sulfate calculations]]<br><br> == 5/16/05 == <br> -Percipitation Lab-<br> -Today we took all the solutions we made last class and did the experiment. We mixed each solution with every other solution recording what happened for every combination.<br><br> == 5/18/05 == <br> -pH webpage-<br> -Today I put the pH of a weak acid calculations on to the website. We all had a mathematical procedure that we had to make a webpage for. They will serve as references to other students. It included a small paragraph, steps for finding the pH, an example that is done out and another parctice problem that the student can do.<br> [[pH calculations of weak acid]]<br><br> == 5/24/05 == <br> -Hollow Penny Lab-<br> -Today we all chose our own labs to do. I chose the Hollow Penny Lab. This was a lab that took a pre and post 1982 penny and compared what happened when they were left overnight in Hydrochloric acid. I had to leave the pennies in over night.<br><br> == 5/25/05 == <br> -Hollow Penny Lab-<br> -Today I finished the hollow penny lab. I took the two pennies that were left overnight in the HCl and put them in water and rinsed them off. Then I made observations on what happened to the pennies and weighed them.<br> [[Hollow Penny Lab]]<br><br> [[Hollow Penny Lab Data]]
