The solubility of nickel(II) carbonate, NiCO3, in water is 0.0448 g/L. Calculate Ksp.

Interpretation Introduction

Interpretation:

The solubility product constant ( Ksp ) of NiCO3   has to be calculated.

Concept introduction:

  • The solubility product constant ( Ksp ) is defined as the equilibrium between compound and its ions in an aqueous solution.
  • Solubility product is the multiplication of concentration of dissolved ion, raised to the power of coefficients.
  • Ionic compound A3B Ksp= [A]3[B] .
  • Molar solubility is defined as amount of solute that can be dissolved in one litre of solution before it attains saturation.

Explanation of Solution

To calculate: The solubility product constant ( Ksp ) of  NiCO3 .

Molar solubility of NiCO3=0.0448 gL×1 mol118.70 g=3.774×10-4mol/L

For calculation convenience consider ''s" as molar solubility of NiCO3
