Red litmus No change No change Blue Mauve
(i) Which of these is - Strongly acidic. Weakly acidic Neutral Basic ?
(ii) Which of the two solutions will react to illustrate the neutralisation reaction ?​

Answer 1

Answer:

A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually. Hence, a pH indicator is a chemical detector for hydronium ions (H3O+) or hydrogen ions (H+) in the Arrhenius model.
