Question

A chemist uses 0.25 l of 2.00 m h2so4 to completely neutralize a 2.00 l of solution of naoh. the balanced chemical equation of the reaction is given below. 2naoh h2so4 right arrow. na2so4 2h2o what is the concentration of naoh that is used?

Answer 1

The concentration of NaOH that is used to completely neutralize is 0.25 Liters.

How do we calculate concentration?

We will calculate the concentration in terms of molarity by using the below formula:

M₁V₁ = M₂V₂, where

M₁ = molarity of H₂SO₄ = 2m

V₁ = volume of H₂SO₄ = 0.25 L

M₂ = molarity of NaOH = ?

V₂ = volume of NaOH = 2 L

On putting all these values on the above equation, we get

M₂ = (2)(0.25) / (2) = 0.25 L

Hence required volume is 0.25 L.
