Question

4) i hot saturated solution of KNO3 forme crystals as it cools. give reason ​

Answer 1

Answer:

The solubility of solids in liquids increases with an increase in temperature and thus hot solutions dissolve more of salt. ... Hence, due to a decrease in the solubility of potassium nitrate salt with a decrease in temperature, its hot saturated solution forms crystals as it cools down.

Answer 2

Answer:

The solubility of ionic solutions is directly proportional to the temperature. At increasing temperatures, solubility increases due to an increase in the kinetic energy of molecules. And as the solution cools down, the solute particles will start to precipitate out.

This is why a hot saturated solution of KNO3 forms crystals as it cools.
