Answer:
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.
