Typically bluish green to green in color. It is a bioavailable form of copper and is an odorless crystalline powder that contains copper and L-gluconic acid, in the form of L-gluconate. Copper Gluconate is easily soluble in water, while it is insoluble in ethanol. It is also preferred over Copper Chloride because of its green compound features.
