Potassium dichromate is usually prepared by the reaction of potassium chloride on sodium dichromate. Alternatively, it can be also obtained from potassium chromate by roasting chromite ore with potassium hydroxide. It is soluble in water and in the dissolution process it ionizes: K 2 Cr 2 O 7 → 2 K + + Cr 2O2− 7 Cr 2O2− 7 + H 2 O ⇌ 2 CrO2−

10 But I thought why not SOX2 S O X 2 While the reaction is stechiometrically correct, it is hard to perform. In excess of HX2S H X 2 S sulfur will be produced. In excess of oxidant sulfate will be produced. And exact balance is impossible to achieve. That said, SOX2 S O X 2 reacts with HX2S H X 2 S finally producing sulfur.

By using jones reagent , we get RCHO group ie , an aldehyde. Jones reagent is a relatively mild oxidising agent. Only a strong oxidising ahent such as chromic acid (H2CrO4) could oxidise an alcohol to carboxylic acid. The oxidising order is as follows -. alkanes -> alcohols -> aldehydes -> carboxylic group. 1 comment.
