Question

Which compound in each pair is more soluble in water?(b) Calcium phosphate or magnesium phosphate

Answer 1

larger is the value of $Ksp$ the higher will the solubility of solid in water.

What is called compound?

• In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
• When the elements come together, they react with each other and form chemical bonds that are difficult to break.
• These bonds form as a result of sharing or exchanging electrons between atoms.

The equation for the dissociation of a solid MX in water is given below

MX(s) ⇄ Mⁿ⁺(aq) + Xⁿ⁻ (aq)

Assume s be the solubility of MX in pure water, then the equilibrium concentrations of ions are

[ Mⁿ⁺] = s

[ Xⁿ⁻ ] = s

The expression for the solubility product constant ($Ksp$) is as follows

$Ksp$ = [ Mⁿ⁺] [ Xⁿ⁻ ]

       = s²

That is, larger is the value of $Ksp$ the higher will the solubility of solid in water.
