Answer Posted / vijay
its because Salts are ionic compounds composed of cations
(positively charged ions) and anions (negative ions) so
that the product is electrically neutral (without a net
charge), and these are the electro-chemical properties that
make them suitable for buffering of electricity from the
copper rod to earth's soil, they work best when they are
dissolved in water becouse that is when the ions are
produced.The layer of charcoal and salt helps to maintain
low
resistance for earth fault currents.Because of ionic
behaviour of salt and charcoal they will maintain moisture
content around the earht pit.
