Then, will make the good cupric basic carbonate and the formic acid responded will dissolve completely to the precipitation, cools to the room temperature, the reduced pressure filtration, with the ethyl alcohol lavation, will pull out filters to does, system blue color four water formic acid copper

Then, made of copper carbonate reacts with formic acid to precipitate dissolved completely, cooled to room temperature, vacuum filtration, washing with ethanol, pumping filter to dry, making four blue water copper Formate.
