potassium dichromate Manufacturer Product Description:
We are actively engaged in offering a qualitative range of Potassium Dichromate for catering the diversified requirements of our clients.
potassium dichromate Manufacturer Features:
Potassium dichromate we manufacturer , 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 acutely and chronically harmful to health.
Acids and bases are added to a system so as to shift the position of a chemical equilibrium(potassium dichromate Manufacturer). The ions have different colors, so that changes are detected visually. Yellow chromate ion turns orange by addition of acid, while the orange dichromate in reaction with bases turns yellow.
1 To make up the the acidified dichromate(VI) solution: dissolve 2 g of potassium dichromate(VI) in 80 cm3 of deionised or distilled water and slowly add 10 cm3 of concentrated sulfuric acid to the solution, with cooling. Label the solution TOXIC and CORROSIVE.
Chromates and dichromates are salts of chromic and dichromic acid. Salts have an intense yellow or orange color, respectively. When solid potassium dichromate (K2Cr2O7) is dissolved in water the resulting solution is orange.
As you can see from the chemical formula, there are two different ions, potassium (K) and chromate (CrO4), which combine to form the compound potassium chromate. An ion is an atom or molecule that carries a net positive or negative charge. The charge of potassium is +1 while chromate is -2.potassium dichromate Manufacturer
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 acutely and chronically harmful to health.
The oxidising agent used in these reactions is normally a solution of sodium or potassium dichromate(VI) acidified with dilute sulphuric acid. If oxidation occurs, the orange solution containing the dichromate(VI) ions is reduced to a green solution containing chromium(III) ions.
Potassium dichromate that we manufacturer is of most premium quality and most affordable price. Once you use our product , you will feel difference within 3 days.
