In laboratory, copper benzoate can be made by combining aqueous solutions of potassium benzoate with copper sulfate. Hydrated copper benzoate precipitates as a pale blue solid: 4 C 6 H 5 CO 2 K + 2 CuSO 4 ·5H 2 O → Cu 2 (C 6 H 5 CO 2) 4 (H 2 O) 2 + 2 K 2 SO 4 + 8 H 2 O. The primary use of this compound is in the production of a blue flame in ...
