Austin Meunier Che 111-007 Lauren Ison Partner: 2/10/11 Lab Procedure For this experiment we will be working with a 0.4-0.5 dried copper salt. First, you need to take the mass of the dried copper salt by using the electronic balance. Second, you will need to use a permanent marker and write your initials on the crucible. Third, record the exact mass of the crucible cover using the electronic balance. Fourth, you will need to place the uncovered sample in the crucible and place on a tile in the oven and approximately 30 minutes till the sample is completely brown. While you are waiting for the sample to turn brown, you will need to start the determining the mass percent of copper. Next, use the tongs to get the crucible out of the oven and then immediately put the lid on the crucible. Once you let the crucible cool off for about 5 to 10 minutes, record the mass. Then pour the dried copper salt into the container marked “Used Copper Salt.” Now get another 0.4-0.5g sample of the copper salt and record the exact mass.
