Question

The weight of the silver (atomic number: 108) displaced by a quantity of electricity which displaces 5600 ml of O2 at STP will be:
  1. 10.8g
  2. 50.0g
  3. 5.4g
  4. 108.0g

A
108.0g
B
5.4g
C
50.0g
D
10.8g
Solution
Verified by Toppr

The correct option is C 108.0g
Solution:- (C) 108g
No. of moles of O2 displaced =560022400=0.25 moles

Molecular weight of O2=32g

Weight of O2=0.25×32=8g=1 Equivalent of O2

Now,
Equivalents of Ag= Equivalents of O2
Molecular weight of Ag=108g

Therefore,
Equivalents of Ag=1

Weight of Ag displaced =1081=108g

Q4
Assertion :A current of 96.5 ampere is passed into aqueous AgNO3 solution for 100 second. The weight of silver deposited is 10.8 g. (Atomic weight of Ag=108). Reason: The mass of a substance deposited during the electrolysis of an electrolyte is inversely proportional to the quantity of electricity passing through the electrolyte.
