Answer 1

If silver chloride is dissolved in water you can say that the equilibrium concentrations of silver and chloride ions are: C A. High B. Moderate C. Low C The solubility of silver chloride in water is: A. High B. Moderate C. Low

AgCl(s) $\rightleftharpoons$ Ag⁺(aq) + Cl^-(aq)

Let us say that the equilibrium concentration of [Ag⁺] = [Cl^-] = x M

Given, K_sp of AgCl = 1.8 x 10^-10

Also,

K_sp = [Ag⁺][Cl^-]

or, 1.8 x 10^-10 = (x)(x)

or, x = 1.3 x 10^-5

Hence, [Ag⁺] = [Cl^-] = 1.3 x 10^-5 M

Thus, the equilibrium concentrations of silver and chloride ions are low.

Hence, the solubility of silver chloride in water is low.
