What is a substance used to identify acids and bases called?

Answer and explanation

Correct answer: Indicator

The governing concept is the use of indicators in acid-base testing. An indicator is a substance that produces a characteristic colour change, or another observable change, in acidic and basic media. Therefore option A, indicator, is correct. A solvent dissolves another substance, a metal is an element or alloy with metallic properties, and a fuel releases energy on burning; none of these definitions specifically describes acid-base identification. Litmus is a familiar example of an indicator.
