Ans 2 :
The solubility of salts increase with increase in temperature. So on a general basis , increasing the temperature , increases the solubility of salt in the solution and vice versa.
This is because , heat causes the increase in kinetic energy of the salt particles due to which their intermolecular forces of attraction break and they are capable of getting dissolved into the solution.

solubility curve of salts
Solubility Curve of Salts ( Extra Credit: Maximum of 5 pts.) The solubility curve for solutes describes at what the temperature its solution will be saturated (maximum solubility). Beyond that amount, the salt will start to crystallize. The solubility of sodium chloride and potassium chloride in water at different temperatures is given in the table below: Naci КСІ Temp (C) Solubility (g/100g H2O) Temp (C) Solubility (g/100g H,O) 0 35.65 28 10 35.72 35.89 20 30...

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
