✨ANSWER✨

SYNTHETIC INDICATORS

2. Phenophthalein indicator - it is colourless.

OLFACTORY INDICATORS
those substance whose is made changes in acidic or basic solution are called olfactory indicator. For example Vanilla extract has a characteristic pleasant smell. If basic solution like sodium hydroxide solution is added to Vanilla extract, then we cannot detect the characteristics of vanilla extract. This can be used as a test tube for acids and bases.
