Lab 6D

A stoichiometry based lab that takes 2 days, a lab day and a results day.

Day 1- On this day it involved getting 25 mL of Na2CO3 solution and 25 mL of CaCl2 solution poured into one beaker. We observed. It looked like a thick milky solution.

We let the solution set aside and moved on to set up the ring stand, filtering apparatus, and beaker. We gingerly poured the solution bit by bit through the filter into to the beaker waiting below. There`s not much to do so we waited.

Once all of the solution drained we took the filter paper out and let it dry overnight until next class.

Day 2-  We weighed the mass of our filter paper and what we got from mixing the two reactants was:

1Na2CO3 + 1CaCl2 - 2NaCl + CaCO3

Basically salt and chalk
