Identify the terms for the following:
The electrode where reduction takes place.
A reddish-brown metal ‘X’, when heated in air, gives a black compound ‘Y’, which when heated in the presence of H2 gas gives ‘X’ back. ‘X’ is refined by the process of electrolysis; this refined form of ‘X’ is used in electrical wiring. Identify ‘X’ and ‘Y’. Draw a well-labelled diagram to represent the process of refining ‘X’.
