Procedure
The zinc chelate of ethylenediamine disuccinic acid is prepared by dissolving 0.0055 moles (1.64 g) of ethylenediamine disuccinic acid in 6.0 grams of deionized water and 3.2 grams of 25 percent NaOH (sodium hydroxide). A sample, 0.005 moles (0.68 g), of zinc chloride is added with stirring. The final pH is adjusted with 25 percent aqueous NaOH solution to a pH of 7.6 and deionized water is added to obtain a final solution containing 2.8 percent chelated zinc.
