Procedure

A stock solution of zinc acetate in aqueous ammonia was prepared by mixing 33.6 parts of glacial acetic acid with 48 parts of water followed by slow addition to the cooled mixture of 18.4 parts of commercial anhydrous liquid ammonia, while maintaining the temperature between 25° and 50° C. After cooling the solution to 10° C., 21.8 parts of zinc oxide were slowly added with stirring while maintaining the temperature below 25° C. The zinc oxide dissolved rapidly to afford a stock solution containing 17.5% weight percent zinc which had a pH of 11.4 and a specific gravity of 1.27.
