What Is The Common Use Of Potassium Oxalate?

Potassium oxalate has several common uses, including:

1. Metal cleaning: Potassium oxalate is used as a metal cleaner to remove rust and tarnish from metals like brass, copper, and bronze.

2. Photography: It is used in photography as a reducing agent for developing photographic films and papers.

3. Bleaching agent: Potassium oxalate is also used as a bleaching agent for certain dyes and fabrics.

4. Medical applications: It has been used in some medical applications such as the treatment of hyperoxaluria, a condition where the body produces too much oxalate that can lead to kidney stones.

5. Laboratory reagent: It is used as a laboratory reagent for analytical chemistry, primarily for gravimetric analysis and titration.

It should be noted that while potassium oxalate has various uses, it can be toxic if ingested or inhaled in large quantities, so caution must be exercised when handling it.
