WebOxidising the different types of alcohols. The oxidising agent used in these reactions is normally a solution of sodium or potassium dichromate (VI) acidified with dilute sulphuric acid. If oxidation occurs, the orange solution containing the dichromate (VI) ions is reduced to a green solution containing chromium (III) ions. WebAldehyde when undergoes oxidation reaction in presence of acidified potassium dichromate or alkaline potassium permanganate forms carboxylic acid as a product. Video Explanation.
