Question

What is the solubility product of a sparingly soluble salt?

Answer 1

Sparingly soluble materials are those, which have lowered solubility. Usually materials are treated as sparingly soluble if 1g of material requires 30 to 100ml of solute to dissolve. In other words, a material will be sparingly soluble if the amount which can be dissolved in 100ml of solute ranges between 1g and 3,3g.

Answer 2

Explanation:

Solubility Product-: Products of the concentrations of ions at constant temperature in a saturated solution of a substance is known as solubility product.

If we put sparingly soluble salt in water and then a very small amount of salt is to be dissolved in the water and finally the salt remains undissolved.

Let we understand it by taking a example of AgCl

If we will put AgCl then very small amount of AgCl will dissolve in water and most of the AgCl will remain undissolved.

* If any solution is in contact with undissolved solute then that condition is said to be saturated solution.
