Amalgamated zinc

Amalgamated zinc is zinc that has been surface treated with mercury to form a surface amalgam containing little contamination from other elements. It is typically used for reduction, and is written as Zn(Hg) in reactions.

Applications[]

• To chemically reduce metallic ions in solution. See Jones reductor.
