Chromium(III) phosphate Wikipedia

Chromium(III) phosphate describes inorganic compounds with the chemical formula CrPO 4. (H 2 O) n, where n = 0, 4, or 6. All are deeply colored solids. Anhydrous CrPO 4 is green. ... Chromium phosphate is prepared by treating a phosphoric acid solution of chromium(VI) oxide with hydrazine.

inorganic chemistry How to test for Chromium(III) Oxide ...

Chromium(III) forms a steel green hydroxide which dissolves in excess strong base to give a deeply green colored solution of the hydroxy complex. Treating this complex with 3% hydrogen peroxide gives the yellow solution of the chromate ion, which upon acidification with dilute nitric acid gives the orange color of dichromate.

Synthesis of chromium (III) acetate

Preparation of chromium (III) acetate. Twentyfive grams of potassium dichromate (or 17g of chromium(VI) oxide) are dissolved in 500ml of water. Sulfur dioxide is bubbled into the solution until reduction to the trivalent state is complete, as indicated by the pure green color of the liquid

Chromium(III) sulfate | Sciencemadness Wiki | FANDOM ...

Chromium(III) sulfate can be more directly produced by the action of cold, dilute sulfuric acid on chromium(III) hydroxide or chromium(III) oxide. It should be noted, however, that many grades of chromium(III) oxide are not reactive enough, often as a result of being calcined, to respond to treatment with acid.
