**How do you find the concentration of a solution in a titration?**

Use the titration formula. If the titrant and analyte have a 1:1 mole ratio, the formula is **molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base**. (Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.)
