Which compound in each pair is more soluble in water?(b) Calcium phosphate or magnesium phosphate
Sidana [21]

<u>larger is the value of </u>Ksp<u> the higher will the solubility of solid in water.</u>

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.
