Formula of a chloride lab

This week the second lab that we performed this week was the formula of a chloride lab. First step in this lab was to take the mass of the beaker in which we would doing the experiment. Next we placed a small amount of zinc in the beaker and re-weighed. Then we got 10 ml of acid and mixed it in the beaker with the zinc. We placed the beaker on a hot plate and heated until all of the acid was gone from the substance. We let this cool for a few minutes and then re-weighed after this reaction.
