Question :(i) Why is acidified water considered to be a good conductor of electricity?
(ii) Write a chemical equation showing the ionic products formed on dissolving potassium hydroxide in water.
(iii) Care must be taken while diluting concentrated nitric acid with water. Why?

The correct answer is -(i) Acidified water contains H+ and OH- ions which can carry an electric current. (ii) K+ and OH- ions are formed on dissolving potassium hydroxide in water: KOH(s) → K+(aq) + OH-(aq) (iii) Concentrated nitric acid is a strong oxidizing agent and when diluted with water, it releases a large amount of heat due to the highly exothermic nature of the reaction. If the acid is added to the water quickly, the heat generated can cause the mixture to splash out of the container, potentially causing harm to the person handling the acid. Therefore, concentrated nitric acid must be added slowly to water with constant stirring to dissipate the heat and prevent splashing.
