# . Calcium sulfate, CaSO4, is only soluble in water to the extent of approximately 2.05 g/L at 25 °C. Calculate Kspfor calcium sulfate at 25°C.

Interpretation Introduction

Interpretation:

The Ksp value for calcium sulfate, CaSO4 at 25°C is to be calculated.

Concept Introduction:

The solubility product is represented by Ksp. The solubility product describes the solubility of the solid substance in the solvent at the particular temperature. The term “solubility product” is only used for those substances that are not completely soluble in water.

Explanation

Calcium sulfate, CaSO4 is only soluble in water to the extent of approximately 2.05g/L at 25°C.

To calculate the solubility of calcium sulfate, CaSO4 in mol/L, the formula used is,

Solubility(mol/L)=SolubilitygL×1molar massmolg

Molar mass of CaSO4 is 136.2g/mol.

Substitute the value of molar mass and solubility (g/L) of calcium sulfate, CaSO4 in the given formula.

Solubility(mol/L)=2.05gL×1136.2molg=1.51×102mol/L

The solubility of calcium sulfate, CaSO4 is 1.51×102mol/L.

The chemical reaction for the solubility of CaSO4 is,

CaSO4(s)Ca2+(aq)+SO42(aq)1
