During titration, the acid and base reacts. In the given, NaOH is the base while KHP is the acid. Since KHP is an acid, it will donate a proton (H+) (based on the Bronsted-Lowry definition).
KHP and NaOH will break up into their ions in the solution and will react as shown:
Balanced Reaction: KHP + NaOH → NaKP + H2O
V NaOH = 19.15 mL
Mass KHP = 0.442 g
[NaOH] = ?
Calculate for the concentration of NaOH using the following steps:
Potassium hydrogen phthalate (KHP) is often used as a primary standard in acid-base titrations. If 19.15 mL of NaOH is required to neutralize 0.442 g of KHP, what is the concentration of NaOH?
