1.	A liquid has a pH less than 7 which represent an acidic solution: (i) State the nature of solution, if its pH increases from 7 to 14. (ii) Mention the ion whose concentration increases with the increase in pH value. (iii) Suggest a method that is generally used for measuring the pH value.
Answer» Solution :(i) There is increase in the strength of alkali, so the nature of solution will be basic. (ii) Hydroxide ION or HYDROXYL ion or `OH^-` ion (III) A PAPER impregnated with the universal indicator is GENERALLY used to measure the pH of a solution.
