Correct Option: A
Here's how to solve this neutralization problem:
-
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.
-
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
-
Determine the moles of H2SO4 needed:
