Claim Text:
1. An antimicrobial soluble copper composition comprising: a solution comprising 10-160 grams/liter hydrated copper sulfate; a basic ammonium salt added to the hydrated copper sulfate solution at 15-60 grams/liter to generate an insoluble copper-ammonium complex; and at least one water soluble acid selected from the group consisting of phosphorous acid and phosphoric acid added to the hydrated copper sulfate solution to solubilize the copper-ammonium complex and to control the pH of the clear blue acid-solubilized copper-ammonium solution thus formed; wherein when present the amount of phosphorous acid is 24-80 grams/liter and wherein when present the amount of phosphoric acid is 17-85 grams/liter; the resulting composition having synergistic antimicrobial properties greater than the antimicrobial properties of each constituent component.
