Jones Reagent



I 'm currently working on my research project. I want to oxidize alcohol to ketone by using jones reagent as oxidizing reagent. I would appreciate it if somebody could help me know how to prepare chromic acid (jones reagent).

Thank you very much,

Add approximately 2 mL of concentrated sulfuric acid to 2 grams of sodium dichromate dihydrite dissolved in 6 mL of water. Should form a carrot orange solution. This is the Jones Reagent.

Jones reagent can be prepared by slow addition of H2SO4 into cold solution of Cr3 in H2O
