Question

2.1 Dissolution of potassium nitrate in water is endothermic. How will the solubility of potassium nitrate change if the temperature of the solution is increased​

Answer 1

Answer:

l don't know this questions

Answer 2

The solubility of the Potassium nitrate solution will Increase if the temperature is increased.

Explanation:

• The formula of Potassium nitrate is $KNO_3$. It is given that the dissolution of potassium nitrate in water is an endothermic process, which means that the solution will get cool.
• If the temperature of the solution is increased, then the solubility of the solution will increase according to Le-Chatelier's principle. The reaction will be favoured on the left side of the equation.
• It can be explained by basic knowledge that if the temperature is increased, the particles of water will go apart with the increase in kinetic energy and thus, the particles of potassium nitrate will be able to dissolve in more amounts.
