What is the equivalent mass of sulfuric acid in the reaction H₂SO₄ + 2 NaOH $\rightarrow$ 2 H₂O + Na₂SO₄?

Question

Quizplus · Accepted Answer

In the balanced chemical equation, the molar ratio between sulfuric acid (HSO4-) and sodium hydroxide (NaOH) is 1:2.

Therefore, the equivalent mass of sulfuric acid can be calculated as:

Equivalent mass = molar mass / n-factor

where molar mass of sulfuric acid = 98.0 g/mol and n-factor = 2 (since 2 moles of NaOH react with 1 mole of H2SO4 to form 2 moles of HSO4-)

Equivalent mass = 98.0 g/mol / 2 = 49.0 g/eq

Hence, the correct answer is D) 49.0 g/eq.
