Description

Purpose
Its primary purpose is to oxidize organic compounds and reduce to Cr(III) in acidic conditions enabling redox reactions for analytical quantification pigment production and corrosion inhibition while posing significant toxicity risks.

General Description
Potassium dichromate is an orange-red crystalline ionic compound with the formula K2Cr2O7 consisting of two potassium cations and a dichromate anion (Cr2O7) where two chromium (VI) atoms share a bridging oxygen in a bitetrahedral structure.
