How much amount of copper sulfate is formed after heating hydrated copper sulfate?

Extracts from this document...


Lab Report Hans Petersen Q. How much the amount of Copper Sulfate will be formed after heating Hydrated Copper Sulfate? Experimental problem How much amount of copper sulfate is formed after heating hydrated copper sulfate? When hydrated copper sulfate is heated the water molecule from hydrated copper sulfate is evaporated and finally the copper sulfate is remained after heating. According to this principle, I can calculate the amount of copper sulfate after the experiment. Variables Independent variable is the amount of hydrated copper sulfate that I use and the dependent variable is the amount of copper sulfate that I get after the process. ...read more.


into the crucible and weighed the mass of the crucible with the hydrated copper sulfate again on the digital scale. Furthermore, I set the tripod and the metal grid, and heated crucible with the Bunsen burner on the tripod. After about 2 minutes I put turned off the Bunsen burner and carried the crucible onto the table and cooled it for a few minutes. Then I put the crucible again on the digital scale and recorded the mass of it. ...read more.


0.8g of water is evaporated from hydrated copper sulfate. Evaluation There could be some errors in measuring the weight of crucible and the digital scale could have been wrong with some errors. Also the heating time was too short to evaporate the water particles in the hydrated copper sulfate. Improving the experiments The more accurate digital scale can improve the experiment and I should not move during measuring the weight of crucible because the scale can react with the movement of wind that I make. Furthermore, I must use completely cleaned crucible for accuracy. Enough time for heating is needed to make copper sulfate from hydrated copper sulfate. ?? ?? ?? ?? ...read more.
