Question

what is solubility product principle and precipitation

Answer 1

Solubility product principle:

Solubility product of a sparingly soluble electrolyte is defined as product of its ions in its saturated condition at 25°C.

• The value of solubility product of a sparingly soluble salt is always constant as given temperature.

If the reaction is :-

• $AB \rightleftharpoons A^+ + B^-$

The solubility principle is defined by the expression :-

• Solubility product, $Ksp = [A^+][B^-]$
