Which are TRUE for the use of indicators with dichromate? Dichromate is orange and changes color to green when reduced. The color change is abrupt enough to serve as an indicator. The equivalence point for dichromate can be determined using Pt and calomel electrodes. Dichromate end points are determined using the distinct color changes of diphenylamine sulfonic acid or diphenylbenzidine sulfonic acid indicators. In basic solution, the orange dichromate solution changes color to yellow when reduced to II IV chromate anion. The color change is abrupt enough to serve as an indicator. O Il and IV O I, II, and IV O l and II O Il and III O l and IV
