What can be said about a small Ksp value?

A. more solid has dissolved

B. less solid has dissolved

C. the solid totally dissociates

D. cannot tell without knowing the Kso value

The correct answer is option B.

Explanation:

Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.

The equation for the ionization of the magnesium hydroxide is given as:

                      xS      yS

Here, S = concentration of compound dissolved in solvent via dissociation

Expression for the solubility product of will be:

As we can see,

Hence, the correct answer is option B.

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers
