If you want to dissolve 91.6 g of kcl in 200 g of water, what temperature should the water be?

The temperature of water will be 60 degree Celsius.

Explanation:

For every chemical there present a particular solubility temperature. The phenomenon occurs as the positive charge is attracted towards the negative and hence gives rise to a cohesive structure. When the polar compounds as well as the ions gets added to the water, they start getting into smaller parts and hence dissolve and becomes solution. The partial charge of water starts attracting different parts of the compound and makes them soluble in water.
