Potassium dichromate

7778-50-9 Potassium dichromate

CAS:: 7778-50-9

MF:: Cr2K2O7

MW:: 294.1846

Use：: Potassium bichromate has significant uses in photographic screen-printing and photography where together with strong mineral acid, they can be used as an oxidizing agent. In the 1850s, gum bichromate printing was largely used in the photographic printing processes. It is worth noting that when exposed to ultraviolet light, a solution of potassium bichromate and gum Arabic will be dried and hardened. Together with concentrated hydrochloric acid (HCL), photochromos and chromium uses potassium bichromate to treat thin and weak negatives of black and white photograph roll. The solution of HCL together with potassium bichromate reconverts the particles of silver in the film to silver chloride. The film is the exposed to actinic light and then redeveloped to its end product, giving out a more stronger negative and a acceptable print. In sulfuric acid, potassium bichromate solution can be used to manufacture a reversal negative.
