How many liters of 4.0 M NaOH solution will react with 0.60 liters 3.0 M H2SO4?

H2SO4 + NaOH - > Na2SO4 + H2O

A. 0.90 L

B. 1.0 L

C. 1.1 L

D. 2.1 L

A. 0.90 L.

Explanation:

NaOH solution will react with H₂SO₄ according to the balanced reaction:

H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O.

1.0 mole of H₂SO₄ reacts with 2.0 moles of NaOH.

For NaOH to react completely with H₂SO₄, the no. of millimoles should be equal.

∴ (MV) NaOH = (xMV) H₂SO₄.

x for H₂SO₄ = 2, due to having to reproducible H⁺ ions.

∴ V of NaOH = (xMV) H₂SO₄ / M of NaOH = 2 (0.6 L) (3.0 M) / (4.0 M) = 0.90 L.
