About this document
Electrochemistry: Gold and Chromium Plating by ScribdTranslations is a document available to read on EtoBox.
The document describes an electrochemical process for refining high-purity gold using the reaction of Au with Cl2 and HCl to produce HAuCl4. Details are provided on how to control the process by measuring the flow of Cl2 and calculating the mass of gold produced for a given current over a specific time. It also describes a process for coating a metal piece with chromium by electrolysis of a Cr+3 solution, calculating the mass and thickness of the deposited chromium.
