Section 4 Experiment#: PROP0375 Separating the Components of a Ternary Mixture Hassan Alhammad 2554122 T.A Katherine Turner 9/11/2014 Introduction The purpose of the experiment is to separate components of mixture of sand (SiO2)‚ salt (NaCl)‚ and chalk (CaCO3). 1. CaCO3+2HCl-----CaCl2+CO2+H2O 2. CaCl2+K2CO3====CaCO3+2KCl The first reaction shows the separation of calcium carbonate from the mixture. In the second reaction we use the product of the first reaction (CaCl2) and change
