What is the role of substances written on the left side of a chemical equation?

Answer and explanation

Correct answer: They are reactants

A chemical equation represents a reaction from left to right. The substances present before the reaction starts are written on the left side and undergo chemical change; they are called reactants. Thus option B is correct. Products are formed during the reaction and appear on the right, whereas indicators and solvents are special substances that may be used in some experiments but are not the general name for the left-hand substances.
