Oxalic Acid and Sodium Hydroxide
H2C2O4 + 2NaOH → Na2C2O4 + 2H2O
Overview
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.
Participants
| Role | Substance | Coefficient | State |
|---|---|---|---|
| Reactant | Oxalic Acid C₂H₂O₄ | 1 | (aq) |
| Reactant | Sodium Hydroxide NaOH | 2 | (aq) |
| Product | Water H₂O | 2 | (l) |
Everyday Example
Oxalic acid is found naturally in rhubarb, spinach, and star fruit. Kidney stones can form from calcium oxalate when dietary oxalate is high.
Industrial Importance
Sodium oxalate is used as a primary standard in analytical chemistry, in metal cleaning, and in the leather tanning process.
