The student needs to think about how the reactions balance out. In the HCl titration, HCl and NaOH react in a 1:1 ratio. In the H₂SO₄ titration, the ratio is 1:2 because each H₂SO₄ gives away two protons, so it needs twice as much NaOH to neutralize it. The student must use these ratios when figuring out the amounts needed to get correct titration results.
reword this using small words The student needs to consider the stoichiometry of the reactions. For the HCl titration, the reaction between HCl and NaOH is a 1:1 molar ratio. For the H₂SO₄ titration, the reaction is a 1:2 molar ratio because each H₂SO₄ molecule donates two protons, meaning it requires twice the amount of NaOH to neutralize it. The student must account for these ratios when calculating the concentrations to ensure accurate titration results.
