Description

[Last Name] 1 Taja Owens Chem 111, 002 Kevin Pedersen Isabella Heestand 09/26/2021 Quantifying Limestone Introduction Limestone is a common sedimentary rock that is composed of calcium carbonate. In this experiment you wanted to determine the percent composition of calcium carbonate in limestone by finding the mass of the product or reactant through two types of filtration. The two types of filtration methods used were, vacuum filtration and gravity filtration. This will help us to the solids from the aqueous solution. To find the exact amount of calcium carbonate that is needed we had to use the following reactions, 1. CaCO3(s) +2HCL(aq) 2. CaCl2(aq) + (NH4)2SO4(aq)

CaCl2(aq) + CO2(g) + H2O(l) CaSO4(s)+2NH4Cl(aq)

The first reaction will produce a gas known as, carbon dioxide and the mass of that can be used to find the mass of calcium carbonate through dimensional analysis. The second reaction will create a solid whose mass will be calculated with the vacuum filtration and will be used to calculate the mass of calcium chloride.
