Chapter 21, Problem 51R

To determine

The solubility of copper sulfate and potassium chloride at 80 $\text{°C}$ by plotting solubility curve to form their saturated solutions.

Explanation of Solution

Introduction:

The solubility of copper sulphate and potassium chloride at 80 $\text{°C}$ is about 93g and 53 g respectively and hence, the saturated solution for both substances can be formed by adding 93g and 53 g of copper sulphate and potassium chloride at 80 $\text{°C}$ in 100g of water.

Conclusion:

Thus,saturated solution of copper sulphate and potassium chloride can be formed at 80 $\text{°C}$ by adding 93g and 53g of copper sulphate and potassium chloride in 100g of water respectively.
