Calculations involving neutralization reactions are usually carried out after performing the titrations. Follow the steps outlined below to solve this type of problems.

Example

Calculate the volume of a 0.200 M KOH solution that is needed to neutralize 25.00 mL of a 0.115 M HCl solution.

Step 1: Write a balanced equation for the neutralization reaction and determine the mole ratio of the acid to base.
