The number of moles of Mohr’s salt required per mole of dichromate is (A) 3 (B) 4 (C) 5 (D) 6 - Find 4 Answers & Solutions | LearnPick Resources Consider a titration of potassium dichromate solution with acidified Mohr’s salt solution using diphenylamine as indicator. The number of moles of Mohr’s salt required per mole of dichromate is a. 3 b. 4 Another important redox titration is titration of Potassium dichromate with Mohr’s salt. Potassium dichromate is also a very strong oxidizing agent ( E° red = +1.33V ) .

Potassium dichromate is also a very strong oxidizing agent (E°red = +1.33V) . However it Potassium Dichromate Titration. In this experiment you will use a standard solution of potassium dichromate (K 2 Cr 2 O 7) to determine the percent by weight of iron (as Fe 2+) in an unknown solid. Dichromate ion reduces to two chromium (III) ions. This reaction requires 6 electrons and 14 (!) hydrogen ions: Cr 2 O 72 - + 14H + + 6 e - ® 2Cr 3+ + Fill the burette by potassium permanganate solution.
