It is studied for the Improvement and exploration of the prepared experiment of the basis carbonate copper in inorganic chemistry. CuSO4 and Na2CO3 as raw material to prepare the Basis Carbonate Copper. The results show that the optimum reaction conditions are as follows ： reaction temperature is 60℃, the ratio of n CuSO4/n Na2 CO3 is 1 ： 1, and pH is about 8. 5, standing time is 48h, the approach is add -back （copper sulfate solution into sodium carbonate solution） . By elemental analysis, IR and X -RD, high purity basic copper carbonate is synthesized
