Potassium Chromate is a yellow, odorless, crystalline (sand- like) solid. It is used as a reagent in analytical chemistry, as a pigment in enamels, paints and dyes, and in metal pickling and plating.
Acidified potassium dichromate solution is an orange solution which changes to green when the alcohol is oxidised. This can be used as a test for alcohols and only alcohols will show the orange to green colour change with acidified potassium dichromate solution.
