Oxalic Acid and Sodium Hydroxide

H2C2O4 + 2NaOH → Na2C2O4 + 2H2O

Visão geral

Oxalic acid is a diprotic organic acid that reacts with two equivalents of sodium hydroxide to form sodium oxalate and water. Oxalic acid is the simplest dicarboxylic acid and is used as a primary standard in acid-base titrations due to its high purity and stability.
