The titration of 25.0 ml of an unknown concentration h2so4 solution requires 83.6 ml of 0.12 m lioh solution. what is the concentration of the h2so4 solution (in m)? question 6 options: 0.20 m 0.40 m 0.10 m 0.36 m 0.25 m

The concentration of the H₂SO₄ is 0.20 M. Titration is a technique used to determine the concentration of an unknown solution through its reaction with another substance. An example of the reactions that are used in titration are acid-base reactions. At the equivalence point, the number of moles of the acid are equal to the number of moles of the base. A color change is observed and the resulting solution is neutral.

The chemical equation for the reaction given is:

H₂SO₄ + 2 LiOH → Li₂SO₄ + 2 H₂O

From the reaction it can be seen that the ratio of the acid and base is 1:2. For every mole of acid neutralized, two moles of the base is used.

To determine the concentration of acid neutralized, remember that at the equivalence point, the number of moles of acid is stoichiometrically equivalent to the moles of base.

Therefore,

To get the concetration of the acid in M, use the the equation below:

To get the molarity of the sulfuric acid:

Since the least number of significant figures in the given is 2, then the final answer must be:
