Chemical Properties
light green powder(s); can be prepared by reaction of nickel with hot dilute phosphoric acid solution; used in electroplating [KIR81] [HAW93]
Physical properties
The heptahydrate is a light apple green powder; decomposes on heating; insoluble in water; soluble in acids and ammonia solution.
Uses
Nickel (Ii) Phosphate is a pigment used in oil and water colors On ignition yields "nickel yellow".
Uses
Nickel phosphate is a greenish powder used in electroplating.
Preparation
Nickel phosphate heptahydrate is obtained as a pale green flocculent precipitate when disodium hydrogen phosphate, Na
2HPO
4 is added to a nickel salt solution. The precipitate is air-dried.
