No, oxalic acid cannot be prepared by adding HCl to a solution of sodium oxalate because oxalic acid is a dicarboxylic acid with two carboxylic acid groups, while sodium oxalate only has one. The reaction would result in the formation of sodium chloride and oxalic acid. The subsequent cooling and filtering steps would help to separate the oxalic acid from the sodium chloride.
The reaction of oxalic acid (H2C2O4) with water (H2O) can lead to the formation of oxalic acid dihydrate. This compound is often used in chemical synthesis and as a reducing agent.
When oxalic acid reacts with ammonium hydroxide, it forms ammonium oxalate and water. The balanced chemical equation for this reaction is: H2C2O4 + 2NH4OH → (NH4)2C2O4 + 2H2O.
The normality of an H2C2O4 solution will decrease if stored in a clear bottle in a lighted room as oxalic acid can photodecompose under light, resulting in a decrease in its concentration and normality.
When potassium dichromate reacts with oxalic acid, it undergoes a redox reaction where the dichromate ion is reduced to chromium(III) ion, and the oxalic acid is oxidized to carbon dioxide and water. The products of this reaction are chromium(III) oxide, carbon dioxide, and water.
