Answer is: less acetic acid to neutralize it.
Balanced chemical reaction of sodium bicarbonate solution and acetic acid: NaHCO₃(aq) + CH₃COOH(aq) → CH₃COONa(aq) + H₂O(l) + CO₂(g).
According to chemical reaction: n(NaHCO₃) : n(CH₃COOH) = 1 : 1.
Stronger solution of sodium bicarbonate (NaHCO₃), more acetic acid (CH₃COOH) is neeed for neutralization.
