The title of the lab that we completed in class was The Law of Conservation of Matter. The purpose of this lab was to find out if matter can be created or destroyed in a chemical reaction. Dalton came up with the atomic theory, which included the law of conservation of matter. His theory was that matter cannot be created or destroyed and that chemical reactions only rearrange the way that atoms are combined; the atoms themselves don’t change. The procedure went like this... 1) Pour 15 ml of Barium Chloride into the bottle.

2) Pour 4 ml of Sodium Sulfate Solution into the test tube. 3) Stand the test tube in the bottle as shown below.
4) Weight the whole apparatus.
5) Record the weight, now turn the bottle over slowly to allow the solutions to mix. Record the new weight. 6) Repeat the procedure, using Potassium Iodine in the bottle and Lead Nitrate in the test tube. After performing the procedures you record your data.
