The solubility of potassium chloride (KCl) and Hydrogen chloride (HCl) for different temperatures is given in the table below: Temperature (degree celsius) 10 20 30 40 50 Solubility (g per 100 ml), KCl 31.2 34.2 37.2 40.1 42.6 Solubility ( g per 100 ml), HCl 75 70 65.5 61 57.5 Let us assume you are asked to dissolve 75 g of HCl completely in a beaker containing 100 mL of water at 40∘C. What should be done?

The solubility of potassium chloride (KCl) and Hydrogen chloride (HCl) for different temperatures is given in the table below:

Temperature (degree celsius) 10 20 30 40 50
Solubility (g per 100 ml), KCl 31.2 34.2 37.2 40.1 42.6
Solubility ( g per 100 ml), HCl 75 70 65.5 61 57.5

Let us assume you are asked to dissolve 75 g of HCl completely in a beaker containing 100 mL of water at 40∘C. What should be done?
