# Solution: The volume required to reach the equivalence point of an acid-base titration depends on the volume and concentration of the acid or base to be titrated and on the concentration of the acid or base used to do the titration. It does not, however, depend on whether or not the acid or base being titrated is strong or weak. Explain.

###### Problem

The volume required to reach the equivalence point of an acid-base titration depends on the volume and concentration of the acid or base to be titrated and on the concentration of the acid or base used to do the titration. It does not, however, depend on whether or not the acid or base being titrated is strong or weak. Explain.

###### Solution

We are asked to explain why the volume to reach the equivalence point is dependent on the volume and concentration of titrant (i.e. acid or base) and analyte (i.e. acid or base) and not on the nature of the titrant and analyte (i.e. strong or weak acid/base).

Remember the analyte refers to the acid or base to be titrated and the titrant refers to the acid or base used to do the titration.

Recall that at the equivalence point of a titration:

Also, recall that moles = molarity × volume

This means:

$\overline{){\left(\mathbf{MV}\right)}_{{\mathbf{acid}}}{\mathbf{=}}{\left(\mathbf{MV}\right)}_{{\mathbf{base}}}}$
