Devise as many ways as you can to experimentally determine the Ksp value of a solid. Explain why each of these would work.

Interpretation Introduction

Interpretation:

The experimental methods used for the determination of Ksp are to be devised and the reason behind their use is to be stated.

Concept introduction:

The salts that do not dissolve completely in a solvent or they show the partial dissociation, for them solubility product that is Ksp is used.

Explanation of Solution

To determine: The experimental methods used for the determination of Ksp and the reason behind their use.

The first method uses the concentration of the species that are present in the solution to calculate solubility product while the second method uses precipitation concept and then the calculation of solubility product from the concentration of ions in the solution.

The first method is explained as,

A solid of known mass and it is added to a solvent whose volume is known. Add the solid in the solvent till the solution becomes saturated. Calculate the number of moles of salt and then find out the concentration of each ion that is present in the formed solution. These values of concentration are then multiplied to obtain the value of solubility product of the salt in the solution.

The second method is explained as,

A solid of known mass is taken and it is then added to a known volume of solvent till the time a saturated solution is formed. A little more amount of water is added to dissolve all the solids in the solution. The solution has now reached the saturated stage and this leads to Q=K
