When solutions of silver nitrate and calcium chloride are mixed, silver chloride

Question

When solutions of silver nitrate and calcium chloride are mixed, silver chloride precipitates out of solution according to the equation:

2AgNO3+CaCl2-->2AgCl+Ca(NO3)2

When solutions of silver nitrate and calcium chloride are mixed, silver chloride precipitates out of solution according to the equation: 2AgNO3+CaCl2-->2AgCl+Ca(NO3)2 What mass of silver chloride can be produced from 1.78 L of a 0.115 M solution of silver nitrate? The reaction described in Part A required 3.31 L of calcium chloride. What is the concentration of this calcium chloride solution?

Explanation / Answer

Moles AgNO3 = 1.16 x 0.176 = 0.204 = moles AgCl Mass AgCl = 0.204 mol x 143.32 g/mol = 29.3 g Moles CaCl2 = 0.204 / 2 = 0.102 M = 0.102 / 3.30 = 0.0309
