ACIDS & BASES AND IONIC REACTIONS

10.5 - Calculations Involving Neutralization Reactions

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

Let's look at this 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. (view work)

Step 2: List the volume and molarity for the HCl and the KOH solutions. (view work)

Step 3: Determine the availability of the number of moles of HCl that is available in the titration.(view work)

Step 4: Apply the mole ratio determined in step 1 to determine the moles of base that is needed to neutralize the available acid. (view work)

Step 5: Divide the moles of base by the given concentration of KOH. (view work)
