Answer to Question #347418 in Chemistry for Indigo Exner

Question

In a titration, 10.0 ml of H2SO4 is required to neutralize 0.0400 mol of NaOH. From this data, the [H2SO4] is?

Answer 1

Solution:

Balanced chemical equation:

H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O

According to stoichiometry:

Moles of H₂SO₄ = Moles of NaOH / 2

or:

2 × Molarity of H₂SO₄ × Volume of H₂SO₄ = Moles of NaOH

Therefore,

Molarity of H₂SO₄ = (Moles of NaOH) / (2 × Volume of H₂SO₄)

Molarity of H₂SO₄ = (0.0400 mol) / (2 × 0.0100 L) = 2.00 mol/L = 2.00 M

The molarity of H₂SO₄ solution is 2.00 M

Answer: The [H₂SO₄] is 2.00 M
