Separating a Mixture of Compounds Exp. No. 2 name Chemistry 145 February 2‚ 2014 I. Purpose The purpose of this experiment was to separate this mixture into components‚ determine the mass and percentage of each component. In addition to test the accuracy of an alternative method of subtraction to find the mass of the sodium chloride directly. Start with a mixture of sand (SiO2)‚ sodium chloride (NaCl)‚ and ammonium chloride (NH4Cl)‚ and use these separation processes: sublimation filtration
