No AgCl is not soluble, the reasoning of it being soluble because NaCl is, is incorrect. NaCl is soluble because it is a group 1 metal. AgCl is no because it forms a precipitate.
Since the [AgCl] term is a constant, which has no effect on the equilibrium, it is built into the equilibrium constant for the reaction. [Ag+][Cl-] = Kc x [AgCl] This equation suggests that the product of the equilibrium concentrations of the Ag+ and Cl- ions in this solution is equal to a constant. Since this constant is proportional to the solubility of the salt, it is called the solubility product equilibrium constant for the reaction, or Ksp.
