Question

QUESTION 20 1 poil The Ksp of AgCl is 1.6 x 10-10. What is the solubility of AgCl in 0.0010 M MgCl2? Give your answer using scientific notation (1.23e-4) and to 2 significant figures (i.e., one decimal place).

Answer 1

Agcs - Agt + ch is the solubility equilibrium of Agcl. In Mach, concentration of CT increases and the equilibrium shifts to left, suppressing the dissociation of Agcl. Thus solubility decreases in Mach (Common in effect) mach Might +2cł 0.00lom 2x0.0010 M = 0.002 M.
