Question

An indicator is used in a titration toshow when _It does this bychanging color.A there has been a change in temperatureB. to add more waterC. an equal number of moles of acid and base are present

Answer 1

Step-by-step explanation

Firstly, we need to define the word titration.

Titration is defined as a technique that is used to determine the known concentration of an unknown solution.

This normally occurs between an acid and a base

During titration, an indicator changes color when equilibrium has been attained between the two solutions. The solutions are normally acid and base. At equilibrium, the number of moles of acid is equal to the number of base.

Therefore, the correct answer is option C
