Question

Enter the solubility-product expression for Al(OH)3(s).

Answer 1

Concepts and reason

Solubility is defined as the maximum amount of solute dissolved in a given amount of solvent to make a saturated solution at a particular temperature.

Molar solubility is the number of moles of solute that will dissolve in a liter of a solution. It is expressed as mol/L or M (molarity).

Fundamentals

Solubility product: The equilibrium constant which defines the solubility of an ionic substance in water is known as a solubility product. The solubility product is denoted by.

For a saturated solution, the solubility product is the product of activities of the ions each raised to its coefficients (powers).

Consider a general reaction:

The solubility product is expressed as follows:

Where,

Solubility product =

Molar solubility of M ion =

Molar solubility of X ion =

The powers raised to the ions =

The equation is as follows:

The solubility product expression is as follows:

Ans:

Solubility-product expression for is .
