Potassium dichromate solution is widely used in analytical chemistry as an oxidizing agent for titrations, particularly in the determination of iron content in ores and other materials. It is also employed in the calibration of spectrophotometers due to its strong absorption characteristics. In organic chemistry, it serves as a reagent for the oxidation of alcohols to aldehydes and ketones. Additionally, it is used in the preparation of cleaning solutions for laboratory glassware, effectively removing organic residues. In the field of histology, it is utilized as a fixative for tissues, preserving cellular structures for microscopic examination. However, its use is declining due to its high toxicity and environmental concerns.
