Define the following terms:
(1) Equivalent conductivity
(2) Corrosion of metals
उत्तर
(1) Equivalent Conductivity: It is the conducting power of all the ions present in a solution containing one gram equivalent of the electrolyte.
(2) Corrosion of Metals: It is the process involving the conversion of the metal surface into undesirable compounds on exposure to atmospheric conditions i.e. moisture and air. It is also called weeping of metals.
