Abstract

Typical demonstrations of lead deposition are usually conducted by reacting aqueous solutions of lead(II) acetate with zinc rods. Here we refer to the less known, also attractive, reaction of plumbate solutions with aluminum. A variety of lead films can be formed depending on the conditions. The method we describe permits obtaining a large lead globule in less than 1 minute. The globule is 1-3 cm in diameter and usually remains floating for a long time.
