ELECTROCHEMISTRY
19951
The mass deposited at an electrode is directly proportional to
1 Atomic weight
2 Equivalent weight
3 Molecular weight
4 Atomic number
Explanation:
It’s obvious.
ELECTROCHEMISTRY
19952
From the solution of which of the following one faraday of electricity will liberate one gram atom of metal
1 \(NaCl\)
2 \(BaC{l_2}\)
3 \(CuS{O_4}\)
4 \(AlC{l_3}\)
Explanation:
(a)Equivalent weight and atomic weight of \( Na\) metal are the same, so \( 1g \) atom of \(Na \) is deposited by one Faraday of current.
ELECTROCHEMISTRY
19953
On electrolysis, \(1\,mole\) of aluminium will be deposited from its molten salt by
1 \(3\,mole\) of electrons
2 \(4\,mole\) of electrons
3 \(2\,mole\) of electrons
4 \(1\,mole\) of electrons
Explanation:
(a) \(Al \to A{l^{3 + }} + 3{e^ - }\).
ELECTROCHEMISTRY
19954
The atomic weight of \(Fe\) is \(56.\) The weight of \(Fe\) deposited from \(FeC{l_3}\) solution by passing \(0.6\) Faraday of electricity is ............. \(\mathrm{g}\)
19951
The mass deposited at an electrode is directly proportional to
1 Atomic weight
2 Equivalent weight
3 Molecular weight
4 Atomic number
Explanation:
It’s obvious.
