Problem 33P

A KNO3 solution containing 45 g of KNO3 per 100 g of water is cooled from 40 °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 33P:

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  KNO3 at 40 °C  is 62 g per 100 g of water whereas the solubility of  KNO3 at 0 °C  is 12 g per 100 g of water. Thus, a KNO3  solution containing 45 g of KCl per 100 g of water is cooled at 40 °C  forms unsaturated solution.

Therefore, the difference between the amount of KNO3  which could be dissolved at 40C and the amount of KNO3  which could be dissolved at 0C will precipitate out of solution.

Thus, when the KNO3  solution having 45 g of KNO3  per 100 g of water cools from from 40 °C to 0 °C, the solution becomes supersaturated and the excess solid precipitates out of solution. When the solution cools slowly,it forms crystals as it comes out of solution.
