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 1 of 3
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....
