One method to oxidize aldehyde is by using acidified potassium dichromate(VI) solution
The step: A small amount of potassium dichromate(VI) solution is acidified with dilute sulphuric acid and a few drops of the aldehyde is added. If nothing happens in the cold, the mixture is warmed gently for a couple of minutes - for example, in a beaker of hot water. The presence of aldehyde will turn the orange solution into green solution.
Question. Is sulphuric acid can be replaced with other acid to acidified the solution? Thanks in advance :)
