Function of Copper Citrate
Copper citrate is soluble in alkaline citrate solutions.
The hydrated salt will lose its water of crystallization at 100 °C, turning from green to blue.
When heated more strongly, the salt decomposes, leaving behind solid copper particles. When heated under vacuum, the residue is
claimed to be pyrophoric.
