## Question:

If 9.71 mL of 0.252 M KOH is used to completely titrate 15.0 mL of HCl, how many moles of HCl are in the solution? Hint: start by writing the balanced chemical equation.

## Titration:

In a titration method, a titrant will react with a sample until it reaches the equivalence point. Therefore, it is important to provide a balanced chemical equation that describes the titration reaction. It will show the amount of titrant needed to react with the sample. For the given problem, we need to establish a balanced chemical equation for potassium hydroxide (KOH) and hydrochloric acid (HCl) in order to determine the moles of HCl present in the solution.
