Answer 1

Answer:

The acidic, basic or neutral solution can be tested by common indicators like litmus, methyl orange and phenolphthalein. More accurately they can be ascertained on the basis of ionisation. Water ionises to a very small extent. The concentration of [H3O+] (aq.) and OH- (aq.) ions in pure water is found to be 1 x 10-7 mol litre-1. This means that all aqueous solutions contain both

[H3O+] (aq.) and OH- (aq.) ions and the product of concentration of these ions is (1x 10-7) (1 x 10-7)

= 1 x 10-14 mol2 litre-2 at 25°C. This is known as ionic product of water (K).
