NaBr is the bottom layer because NaBr has a density of 3210 kg/m3. For experience 4d: Question 1. Presumably I have an acidic compound and a neutral compound in the mixture. The acid is represent by RCOOH. So with the NaOH added‚ it form the sodium salt (which is soluble in water and the neutral compound is not). RCOOH goes to RCOONa. Then I separate the layers‚ add HCl to the RCOONa which forms the original acid and that is what is precipitating. If I have all of the acid removed from the mixture

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
