Describe the basic technique of replica plating. Replica plating is a transfer technique that may be used to produce multiple copies of a particular colonial arrangement on a number of agar plates.
Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology.he traditional solution used for industrial hard chrome plating is made up of about 250 g/L of CrO 3 and about 2.5 g/L of SO 4 â . In solution, the chrome exists as chromic acid, known as hexavalent chromium. A high current is used, in part to stabilize a thin layer of chromium(+2) at the surface of the plated work.
