Procedure

Ten ml of 17% zinc solution were added to a liter of water. Later 20 grams of potassium phosphate were added and dissolved. Zinc phosphate formed a precipitate. Phosphorous acid was then added to lower the pH and clear the solution. Once clear 30 ml of the solution prepared in example 35 was added. This acidic solution, which was acidic, then remained undisturbed for a day, after which the pH was adjusted to 10 with the addition of MEA. The zinc solution comprising chelated zinc remained clear, free of precipitates, and colorless.
