What is the solubility of AgCl when it is in a solution of 0.15 M NaCl? (AgCl has Ksp = 1.8 x 10-10.) Make a reaction table. Include rows for initial concentration, change in concentration, and equilibrium concentration. Write down the equation for the Ksp of the reaction. What is the concentration of Cl-? Plug that number into the Ksp equation to determine the solubility of AgCl when it is in a solution of 0.15 M NaCl .
