ELECTROCHEMISTRY
19813
The atomic weight of silver and copper are \(108\) and \(64\). A silver voltameter and a copper voltameter are connected in series and when current is passed \(10.8\, gm\) of silver is deposited. The mass of copper deposited will be ............. \(\mathrm{gm}\)
19814
Faraday's laws of electrolysis are related to
1 The atomic number of positive ion
2 The equivalent weight of electrolyte
3 The atomic number of negative ion
4 The velocity of positive ion
Explanation:
Faraday's first law of elecrolysis : This law states that "The amount of a substance deposited or dissolved at an electrode is directly proportional to the charge passing through the electrolytes. Faraday's second law: This law states that the amounts of different substances deposited at electrodes by passage of the same quantity of electricity are proportional to their chemical equivalent(\(E\)).
ELECTROCHEMISTRY

In the process of electrolysis, the current is carried out inside the electrolyte by
1 Electrons
2 Atoms
3 Positive and negative ions
4 All the above
Explanation:
Electrolyte Solution or molten salt can conduct electricity by the process of electrolysis. In electrolytes, current is carried by positive and negative ions, rather than by electrons. For example, in a lead-acid car battery, the electrolyte is dilute sulphuric acid, which contains negative sulphate ions and positive hydrogen ions.
