Lab 6D

Last class we did 6D, where we mixed NaCO3 and CaCl2 together. A double replacement reaction during the mixing process. Precipitate, salt (NaCl2) was formed. The liquid turned white and cloudy from transparent. We measured the mass of the filter paper. In day 2, which is tomorrow, we will weigh the filter paper again and see if the mass has changed since it has absorbed Calcium Carbonate.
