What volume of a 0.224 M perchloric acid solution is required to neutralize 26.0 mL of a 0.149 M calcium hydroxide
solution?
2req

Answer 1

Explanation:

What to find? The volume of perchloric acid

Firstly, we need to write the balanced equation of the reaction

`HClO_(4(aq))\text{ + }Ca(OH)_(2(aq))\rightarrow\text{ }H_2O_((l))\text{ + }Ca(ClO_4)_(2aq))`

Given the following parameters

The concentration perchloric acid = 0.224M

The concentration of Calcium hydroxide = 0.149 M

The volume of Calcium hydroxide = 26.0mL

The volume of perchloric acid =?

Recall that the equivalentce point of a titration is

mole acid = mole base

Mole = Molarity x volume
