Dichromate vs bichromate

Did you know?

Web¶3.8.1.1 mentions a "5% aqueous solution of sodium or potassium dichromate". For chemistry nuts, this begs the question as to whether the dihydrate salt (Na2Cr2O7-2H2O) or pure dichromate (Na2Cr2O7) is intended. Given that the dihydrate is the most common form, most anodizers are weighing out 50 g/L of the dihydrate to make up a seal tank. WebBoth of these tanks contain solutions with concentra- tion of 5 to 9 ounces per gallon (oz/gal) sodium dichromate. The pH is maintained between 5.0 and Processes undergoing research and development (R&D), as well as commercially available processes, were considered.
