Alloys, ornamental gold and brass are prepared by electroplating by chemical reactions between metals and non-metals.
By electroplating a costly metal like gold is cast upon a cheaper metal like silver in order to give a gaudy appearance.
Ornamental gold is mostly electroplated.
Alloys are made by combining two or more metals, non-metals or both that retain the properties of both by means of chemical reactions.
