A universal indicator shows orange colour in a solution. What could be the nature of the solution?

Answer and explanation

Correct answer: Acidic

A universal indicator is a mixture of indicators that gives different colours over the pH scale. Orange generally corresponds to an acidic pH, usually more acidic than yellow but less strongly acidic than red. Therefore, option A is the appropriate conclusion. Green is associated with a nearly neutral solution around pH 7, while violet or purple suggests a strongly basic solution. The colour indicates the solution’s acid-base nature, not whether it contains a metal.
