Hard chemistry question...solubility?

Question

Calculate the solubility (in grams per liter) of silver chloride in the following:

(a) pure water

(b) .025 M BaCl2

(c) 0.17 M AgNO3

ALSO, here's another problem I couldn't get the answer to....

A solution is prepared by mixing 13.00 mL of .0021 M aqueous Hg(NO3)2 with 25mL of.015M HCl. Assume that volumes are additive.

(a) Will precipitation occur?

(b) Calculate [Hg2^2+], [Cl^-], and [NO3^-] after equilibrium is established?

Thanks so much for your help!!

Answer 1

too hard

Answer 2

You have to make a saturated solution of AgCl in each of the substances by slowly adding AgCl to it and allowing it to dissolve. Once the solution is saturated you find out the weight of the solute dissolved. Ensure that the entire operation is isothermal, because solubility is a function of temperature.

Standard solubility data is available in literatures.
