What is the charge of CrPO4?

The charge on the phosphate ion is 3-, PO43- . The formula for phosphate of chromium is CrPO4.

Is AgBr soluble or insoluble in water?

Silver bromide (AgBr), a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light.

Why is chromium ( III ) phosphate not soluble in water?

Although chromium (III) phosphate is hardly soluble in water, overexposure to the compound from the environment, industrial location and abrasions from metal on metal implants could have harmful effects.

How is CRPO 4 catalyzed to adsorb divalent cations?

Studies reveal that CrPO 4 catalyzes the adsorption of divalent cations onto its amorphous surface through the cation exchange mechanism. The mechanism suggests that the H+ ions are liberated from the solid to aqueous phase as the cations become hydrolyzed and adsorb onto the catalyst surface.

Which is more soluble in water MgCrO4 or MgSO3?

MgCrO4 is soluble in water; MgSO3 is slightly soluble in water. 6. The sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insoluble in water. BaS, CaS, and MgS are sparingly soluble.

What are the rules for the solubility of water?

The Solubility Rules 1. The nitrates, chlorates, and acetates of all metals are soluble in water. Silver acetate is sparingly soluble. 2. All sodium, potassium, and ammonium salts are soluble in water.
