Question

solubility product of sparingly soluble salt​

Answer 1

The solubility of any sparingly soluble salt is almost always decreased by the presence of a soluble salt that contains a common ion.

Answer 2

Answer:

$\huge\bigstar\underline\blue{Answer}$

Adding a common cation or common anion to a solution of a sparingly soluble salt shifts the solubility equilibrium in the direction predicted by Le Chatelier's principle. The solubility of the salt is almost always decreased by the presence of a common ion.

Which salt determines solubility?

$\huge\bigstar\underline\pink{</strong><strong>Answer</strong><strong>}$

Salts containing nitrate ion (NO3-) are generally soluble. Salts containing Cl -, Br -, or I - are generally soluble. Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+. Thus, AgCl, PbBr2, and Hg2Cl2 are insoluble.Aug 15, 2020
