    Answer question numbers (a) – (d) on the basis of your understanding of the following paragraph and related studied concepts. The process of dissolving an acid or a base in water is a highly exothermic one. Care must be taken while mixing concentrated nitric acid or sulphuric acid with water. The acid must always be added slowly to water with constant stirring. If water is added to a concentrated acid, the heat generated may cause the mixture to splash out and cause burns. The glass container may also break due to excessive local heating. Look out for the warning sign on the can of concentrated sulphuric acid and on the bottle of sodium hydroxide pellets. Mixing an acid or base with water results in decrease in the concentration of ions (H_3O^+//OH^-) per unit volume. Such a process is called dilution and the acid or the base is said to be diluted. What is meant by dilution of an acid or a base ?
