Activity 22.1
Take an aqueous solution of
table salt (Sodium Chloride) in a DQRGH
small glass vessel with a wide
FDWKRGH
mouth or a plastic disposal cup.
To this solution, add a little
Turmeric powder (Haldi). The
solution turns yellow. Project

yellow turmeric. Reverse the connection, red colouration found in the
opposite end.

Faraday’s Laws of Electrolysis
First Law : The mass of substance deposited or collected at either
electrodes during electrolysis is proportional to the current
and to the time. If ‘m’ is the mass of substance deposited or
collected at the electrode then
