Correct Option: A

Here's how to solve this neutralization problem:

  1. Write the balanced chemical equation:

    H2SO4 (aq) + 2NaOH (aq) -> Na2SO4 (aq) + 2H2O (l)

    This equation shows that 1 mole of H2SO4 reacts with 2 moles of NaOH.

  2. Calculate the moles of NaOH:

    Moles = Molarity × Volume (in liters) Volume of NaOH = 20 cm3 = 0.020 dm3 Moles of NaOH = 0.1 mol/dm3 × 0.020 dm3 = 0.002 moles

  3. Determine the moles of H2SO4 needed:

    From
