Question

The equation for the neutralization reaction is:

H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)

The concentration of the sodium hydroxide solution is 0.02 mol/dm³. Calculate the concentration of sulfuric acid.

a. 0.01 mol/dm³
b. 0.02 mol/dm³
c. 0.04 mol/dm³
d. Not Mentioned

Answer 1

The concentration of sulfuric acid in the neutralization reaction can be determined by using the balanced chemical equation and the given concentration of sodium hydroxide solution.

Step-by-step explanation:

The concentration of sulfuric acid can be determined by using the balanced chemical equation and the given concentration of sodium hydroxide solution. The balanced equation for the neutralization reaction is:

H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)

According to the equation, the stoichiometric ratio between sodium hydroxide and sulfuric acid is 2:1. Since the concentration of sodium hydroxide is 0.02 mol/dm³, the concentration of sulfuric acid is 0.01 mol/dm³ (half of the concentration of sodium hydroxide).
