How many moles of H₂SO₄ can be completely neutralized by 0.10 mol of NaOH, assuming both acidic protons react?
A.0.10 mol
B.0.20 mol
C.0.050 mol
D.0.010 mol
Explanation
Core Concept
The balanced reaction H₂SO₄ + 2 NaOH → Na₂SO₄ + 2 H₂O shows a 2 to 1 mole ratio of NaOH to sulfuric acid. Dividing 0.10 mol NaOH by 2 gives 0.050 mol H₂SO₄. Neutralization bookkeeping runs on stoichiometric coefficients, not molar masses.
Correct Answer
C0.050 mol
