Question

What happens when KCl is added to H2O

Answer 1

Dear friend, when KCL is added to water then the ions are hydrated. The polar watermolecules are attracted by the charges on the K+ and Cl−ions. ... Let us consider what happens at the microscopic level when we add solid KClto water.

Answer 2

Potassium chloride does not react with water. It will dissolve though, resulting in ionisation. These ions may be separated out by electrolysis, resulting in free chlorine which is highly reactive though, and metallic potassium which does react with water. To get these elements by themselves, you can pass electricity through a vat of molten potassium chloride
