Product Code ::RXSOL-60-6605-283
Categories: Lab Chemical-60
Product Short Description: POTASSIUM DICHROMATE AR
Product Description:

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.

Product Application:

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.

Product Dose:

Primary and secondary alcohols are oxidized by K2Cr2O7 to carboxylic acids and ketones respectively. The oxidation is physically observed by the change in color upon reduction of Cr6+ (yellow) to Cr3+ (blue). This demonstration also illustrates the chemistry behind the breathalyzer test.

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 AR

Product Tag Identification:
Product Useful Area:

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.

Keyword:

Potassium Dichromate is a versatile, Powerful Oxidizing agent (although not as powerful as Potassium Permanganate) that also meets the requirements of being a primary standard.
