Answer :
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.
