Problem 34P

A KCl solution containing 42 g of KCl per 100 g of water is cooled from 60 °C to 0 °C. What happens during cooling?(see Figure 1)

Figure 1 Solubility of some ionic solids as a function of temperature

Step-by-Step Solution:
Step 1 of 3

Solution 34P:

The solubility of a solid in a solution is dependent on temperature. Thus the solubility of most solids in water increases with increasing temperature.

From the figure 1., it is observed the solubility of  KCl at 60 °C  is 45 g per 100 g of water whereas the solubility of  KCl at 0 °C  is 28 g per 100 g of water. Thus, a KCl solution containing 42 g of KCl per 100 g of water is cooled at 60 °C  forms unsaturated solution....
