Zinc dihydrogen phosphate, chemical formula Zn(H2PO4)2·2H2O. Molecular weight 295.38. White triclinic crystal or white solidified substance. Deliquescent. Stable in air at room temperature, decomposes at 100oC and in water. Contains high free acid and is highly corrosive. In the electroplating industry, zinc dihydrogen phosphate can be used for anti-corrosion coating of ferrous metals (its performance is better than that of manganese dihydrogen phosphate), a new agent for phosphating the surface of steel parts, a colorant in the ceramic industry, a clarifier in the glass industry, and an analytical reagent and preservative.
