Heating nickel sulfate dehydrates it, and then 700° it loses sulfur trioxide, sulfur dioxide and oxygen. Other important nickel compounds in this class are nickel carbonate, nickel nitrate, and nickel phosphate
Aqueous solutions of nickel sulfate react with sodium carbonate to precipitate nickel carbonate, a precursor to nickel-based catalysts and pigments. [6] Addition of ammonium sulfate to concentrated aqueous solutions of nickel sulfate precipitates Ni(NH 4) 2 (SO 4) 2 ·6H 2 O. This blue-coloured solid is analogous to Mohr's salt, Fe(NH 4) 2 (SO ...
Nickel maleate can be made from maleic acid and nickel carbonate in boiling water. A dihydrate crystallises from the water solution. [11] Nickel fumarate prepared from fumaric acid and nickel carbonate is pale green as a tetrahydrate, and mustard coloured as an anhydride. It decomposes when heated to 300° to 340° in vacuum.
Nickel(II) carbonate describes one or a mixture of inorganic compounds containing nickel and carbonate. From the industrial perspective, an important nickel carbonate is basic nickel carbonate with the formula Ni 4 CO 3 (OH) 6 (H 2 O) 4. Simpler carbonates, ones more likely encountered in the laboratory, are NiCO 3 and its hexahydrate.

Heating nickel sulfate dehydrates it, and then 700° it loses sulfur trioxide, sulfur dioxide and oxygen. Nickel sulfite can be formed by bubbling sulfur dioxide through nickel carbonate suspended in water. A solution is formed that slowly loses sulfur dioxide, and which crystallises nickel sulfite hexahydrate.
Potassium carbonate is the inorganic compound with the formula K 2 C O 3. It is a white salt, which is soluble in water and forms a strongly alkaline solution. It is deliquescent, often appearing as a damp or wet solid. Potassium carbonate is mainly used in the production of soap and glass. [3]
Major potassium chemicals are potassium hydroxide, potassium carbonate, potassium sulfate, and potassium chloride. Megatons of these compounds are produced annually. [72] KOH is a strong base, which is used in industry to neutralize strong and weak acids, to control pH and to manufacture potassium salts.
