Frequent Uses

Histology and Microscopy

Oxalic acid is sometimes used in tissue staining and microscopy, particularly in staining protocols that involve calcium-based compounds. It helps in the preparation of histological samples by dissolving unwanted calcium deposits.

Preparation of Metal Complexes

Reacts with various metal ions, forming stable metal-oxalate complexes. These complexes are used in research for studying metal-ligand interactions, and as reagents in metal extraction processes.

Preparation of Other Chemicals

Oxalic acid can be used to prepare oxalate salts of various metals. These salts are important in chemical syntheses, as intermediates for other chemical processes or as reagents in various reactions.

Titration and Standardisation

Oxalic acid is commonly used in acid-base titrations to standardise solutions of bases (such as sodium hydroxide). Its known molar mass and reactivity make it ideal for preparing primary standard solutions.

• Metal cleaning and rust removal
• Wood bleaching and restoration
• Analytical chemistry (reagent in titration, pH adjustment)
• Textile and fabric industry (dyeing processes, bleaching agent)
• Pharmaceutical and cosmetic applications
• Cleaning agent and descaler (removal of limescale, hard water deposits)
