• The electroplating of chromium on metal object is called chrome.
• This procedure is used to reduce corrosion and for decorative purpose.
• Trivalent chromium plating is done on graphite to avoid oxidation reaction taking place in it. Here, chromium chloride or chromium sulfate is used for electroplating where Cr³⁺ ions are produced.
