Product Short Description: POTASSIUM DICHROMATE LR
Product Description:

Potassium Dichromate, K2Cr2O7, is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. As with all hexavalent chromium compounds, it is potentially harmful to health and must be handled and disposed of appropriately.

Product Application:

Potassium Dichromate is an odorless, Orange to Red, crystalline (sand-like) solid or powder. It is used as an analytical reagent and in Tanning, Painting, Printing, Electroplating and Pyrotechnics.

Product Dose:

Potassium dichromate is a weaker oxidizing agent than KMnO4 or Ce(IV). However, it is a primary standard and its solutions have long lasting stability in acid and are stable to light, to most organic matter, and to chloride ion. ... If needed, a K2Cr2O7 solution can be standardized against pure iron.

Product Note:

Potassium Dichromate is used for preparing strong cleaning solutions for Glassware and for Etching materials. It also has uses in leather tanning, photographic processing, cement, and wood staining.

Potassium Dichromate is commonly used in acid solution to standardize Ferrous salt solutions using Ferroin indicator:

Cr2O72- + 6 Fe2+ + 14 H+ → 2 Cr3+ + 6 Fe3+ + 7 H2O

Potassium Dichromate is also used to standardize Sodium Thiosulfate solutions. In acidic solution, Potassium Dichromate oxidizes Potassium Iodide to Iodine; the Iodine thus generated can then be titrated with the Thiosulfate solution using Starch Indicator:

Cr2O72- + 6 I- + 14 H+ → 2 Cr3+ + 3 I2 + 7 H2O

Hexavalent Chromium compounds (the form present in the Dichromate ion) are carcinogenic, and this fact should be considered when evaluating Potassium Dichromate against other oxidizers such as Ceric Sulfate, Potassium Iodate and Potassium Permanganate.
