subacetate of Copper (verdegris) occurs in masses, or as a greenish powder.
Among external refrigerants are cold water, evaporating lotions, weak solutions of subacetate of lead, &c.
In such case, before making up to the mark, a saturated solution of subacetate of lead is added.
A subacetate of lead is formed by digesting a cold solution of uncrystallized acetate, over litharge, with frequent agitation.
After adding the solution of subacetate of lead the flask must be gently shaken, so as to mix it with the sugar solution.
This process was modified by Lassen, who precipitated the aqueous solution with the subacetate of lead.
subacetate of Copper, Subchloride, and Carbonate, all act very similarly to the sulphate when given in large doses.
