April 2025, question 39
Classification · Classification: GRIs, notes and headings
What is the CLASSIFICATION of an apparatus for electroplating flatware made up of silver anodes, an electrolytic solution, and a direct-current (DC) power source? The apparatus is designed for silver anodes and brass (copper-zinc) flatware cathodes to be immersed in the electrolytic solution. The apparatus functions by applying a positively- charged electric current through the anodes and a negatively-charged current through the cathodes. These charges cause silver atoms to dissolve in the electrolytic solution and move toward the negatively-charged brass flatware, thereby coating the brass flatware with silver.
