A 25.00 mL sample of an H2SO4 solution of unknown concentration is titrated with a 0.1322 M KOH solution. A volume of 41.22 mL of KOH is required to reach the equivalence point. What is the concentration of the unknown H2SO4 solution? Express your answer in molarity to four significant figures.

Explanation:

Volume of = 41.22 mL

Molarity of = 0.1322 M

Number of moles of

2 moles of reacts with 1 mole of

So,

of reacts with M mole of

Volume of

Concentration of is

The concentration of the unknown solution is .
