  1. Question 1

    Q1. A 25.0 mL sample of H₂SO₄ is titrated with 0.100 M NaOH. The endpoint is at 30.0 mL. What is the H₂SO₄ concentration?

    • A) 0.0600 M
    • B) 0.120 M
    • C) 0.240 M
    • D) 0.0300 M

    Answer: 0.0600 M

    Explanation: [2×0.100×0.030]/0.025 = 0.0600 M. B ignores 1:2 stoichiometry.
