A student is curious about the Ksp value for NaCl. The student looks up the value om the appendix of his textbook but cannot find a value for NaCl. Why not?

The solubility product Ksp is mostly listed for substances that have very little solubility in water.

Ksp is an equilibrium constant that shows the degree to which a substance dissolves in water to form its ions. Given a hypothetical ionic substance AX which dissociates in solution as follows;

AX(s) ⇄ A^+(aq) + X^-(aq)

The Ksp of the substance therefore is;

Ksp = [A^+] [X^-]

The Ksp of substances is very important for substances that are slightly or sparingly soluble in water. The Ksp of highly soluble substances such as NaCl is often not listed in literature.

Given :

The student looks up the value of the appendix of his textbook but cannot find a value for NaCl.

To Find :

Why the Ksp of NaCl is not present .

Solution :

Ksp values are given for those compounds which are partially soluble or insoluble in water .

But , we know NaCl is strong electrolyte and it completely dissociated in water .

So , the reaction go forward and their is no need to calculate Ksp .

Therefore , the Ksp of NaCl is not present .

Hence , this is the required solution .

i think it is true since you can test the answer and can use observations to complete it.
