Question

Which of the following is not an application of a solubility product?
(A) Predicting precipitation formation
(B) Predicting solubility of sparingly soluble salt
(C) Predicting ph of buffer solution
(D) Qualitative analysis

Answer 1

Hint: A property of a substance known as solute when it gets dissolved in a solvent in order to form a solution is called a solubility product. When it comes to ionic compounds the solubility in water will vary to a great deal. It is denoted by $K_{sp}$

Complete answer:
Predicting ph of a buffer solution is not the application of a solubility product. The following are the applications:
-It helps in predicting the formation of a ppt
-It helps in predicting the solubility of sparingly
-It helps in purification of common salt
-It helps in salting of our soap
-It helps in qualitative analysis
-It helps in calculation of remaining concentration after ppt
-It helps in calculation of simultaneous solubility.

Additional Information:
The solubility of the ionic compound is described as the concentration of ions in equilibrium with a solid. The solubility of the compound will be based on the assumption that the solute exists as a discrete ion and will differ from the actual solubility.

Note:
Solubility depends on the many parameters of which lattice enthalpy of salt and salvation enthalpy of ions in the solution are important. Solubility is temperature dependent. The equilibrium constant is dimensionless because it has quantity is dimensionless. This constant is usually divided by the quotient of activity.
