Back

A highly pure substance used to determine the concentration of a solution.

Front

What is the role of an indicator in titration?

Back

To signal the end point of the titration by changing color.

Front

What is the formula to calculate moles from concentration and volume?

Back

Moles = Concentration (mol/dm³) × Volume (dm³).

Front
