Procedure

Aqueous solutions of a group of magnesium, calcium and zinc salts were prepared by mixing 0.06 moles of the organic acid with 0.033 moles of either magnesium hydroxide, calcium hydroxide or zinc oxide in 780 g of water, then heating the mixture to the reflux temperature with stirring for three hours followed by cooling to room temperature and filtering. A magnesium stearate solution was prepared by heating excess commercial magnesium stearate in water with stirring for four hours followed by cooling and filtering. The metal content of each solution was estimated by atomic absorption.
