Problem #2: Potassium dichromate is used to titrate a sample containing an unknown percentage of iron. The sample is dissolved in H 3 PO 4 /H 2 SO 4 mixture to reduce all of the iron to Fe 2+ ions. The solution is then titrated with M K 2 Cr 2 O 7, producing Fe 3+ and Cr 3+ ions in acidic solution. The titration requires mL of K 2 Cr 2 O 7 for g of the sample.
· NCI Thesaurus (NCIt) Potassium dichromate is a potassium salt that is the dipotassium salt of dichromic acid. It has a role as an oxidising agent, an allergen and a sensitiser. It contains a dichromate (2). Potassium bichromate appears as orange red crystals. Denser than water and soluble in .
