(b) Electrolysis
(c) Electrodes
(d) Electrorefining of metals​

Answer 1

Answer:

: refining of a metal (such as copper) by electrolysis, the crude metal used as the anode going into solution and the pure metal being deposited upon the cathode

— called also electrolytic refining

Answer 2

$\mathcal{\huge{\fbox{\purple{Solution:-}}}}$

State the meaning of the terms :-

✴ Electro-magnetic induction :- Electromagnetic Induction is a current produced because of voltage production due to a changing magnetic field.

✴ Electrolysis :- Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form.

✴ Electrodes :- The electrode, it is any substance that is a good conductor of electricity and these substances usually connect nonmetallic parts of a circuit for example semiconductors, an electrolyte, plasmas, vacuum or even air.

✴ Electrorefining of metals :- Electrorefining is a process used to make impure copper pure. The smelting process takes copper ore and processes it into metal. This metal (sometimes called "blister copper" contains other metals. These other metals often include gold, silver, arsenic and others.
