Question

addition of small amount of acid or salt in water makes?​

Answer 1

Answer:

Water is a covalent compound, hence pure water is a weak electrolyte and feebly ionised and thus bad conductor of electricity.

However, addition of a small amount of acid or alkali increases ionisation of water making at good conductor of electricity.

For example, To increase the conductivity of water a few drops of sulphuric acid is added. Being a strong acid it can ionize completely to release H+ ions. These H+ ions are responsible for the conduction of electricity.

Answer 2

Answer:

Salts that contain small, highly charged metal ions produce acidic solutions in water. The reaction of a salt with water to produce an acidic or a basic solution is called a hydrolysis reaction.
