Is chromium III phosphate a solid?
Chromium(III) phosphate describes inorganic compounds with the chemical formula CrPO4(H2O)n, where n = 0, 4, or 6. All are deeply colored solids.
Is chromium phosphide soluble in water?
Chromium(III) phosphate is an inorganic compound with the chemical formula CrPO4. CrPO4 normally exists as a green crystal, CrPO4•4H2O, or a violet crystal, CrPO4•6H2O, in its hydrated form. It is insoluble in water but soluble in acids.

What color is chromium?
Chromium is a lustrous, brittle, hard metal. Its colour is silver-gray and it can be highly polished. It does not tarnish in air, when heated it borns and forms the green chromic oxide.
Is chromium toxic to humans?
Human studies have clearly established that inhaled chromium (VI) is a human carcinogen, resulting in an increased risk of lung cancer. Animal studies have shown chromium (VI) to cause lung tumors via inhalation exposure.
How many isomorphs can a chromium(III) phosphate exist as?
Chromium (III) phosphate can exist as two isomorphs. Its β-isoform is orthorhombic with the Cmcm space group (a = 0.5165, b = 0.7750, c = 0.6131 nm). The structure consists of infinite chains of trans edge-sharing CrO 6 octahedra, which run parallel to the c-axis, and are linked by PO 4 tetrahedra.
What is the melting point of chromium(III) phosphate?
Chromium (III) phosphate. It is insoluble in water but soluble in acids. The melting point of CrPO 4 stands at a temperature of 100 °C however it is a stable compound at normal temperature and pressure. Chromium (III) phosphate undergoes thermal decomposition at a high temperature of 1450 °C to yield chromium oxide and phosphorus pentaoxide.
How do you make anhydrous chromium III phosphate?
The preparation of anhydrous chromium(III) phosphate begins by grinding a mixture of 75 mol% of chromium(III) oxide, Cr2O3, and 25 mol% of pure ammonium hydrogen phosphate, (NH4)2HPO4. This mixture is pressed into pellets and heated under air pressure at 400 °C for 24h in order to remove ammonia and water.
What is chromium III phosphate paint used for?
Paints containing chromium (III) phosphate have been used as corrosion resistant coating for metals. The paints consist of aqueous acidic chromium (III) phosphate solution which convert to a consistent film when applied onto metals heavily used in manufacturing and utility such as zinc, zinc alloy, aluminum and aluminum alloy substrates.
