In the titration of H₂SO₄ with NaOH, 40.0 mL of 0.100 M NaOH neutralizes 20.0 mL of H₂SO₄. What is the H₂SO₄ molarity?
A.0.100 M
B.0.200 M
C.0.0500 M
D.0.400 M
Explanation
Core Concept
Moles NaOH = 0.100 × 0.0400 = 0.00400 mol. Each H₂SO₄ needs 2 NaOH, so moles H₂SO₄ = 0.00200 mol; M = 0.00200 ÷ 0.0200 = 0.100 M.
Correct Answer
A0.100 M
