Acetates, as'e tayts, salts of acetic acid. The acetates of most commercial or manufacturing importance are those of aluminum and iron, which are used in calico-printing; of copper, which, as verdigris, is used as a color; and of lead, best known as sugar of lead. The acetates of potassium, sodium and ammonium, of iron, zinc and lead, and the acetate of morphia, are employed in medicine.
