19 g of moltenSnCl2is electrolysed for sometime using inert electrodes. 0.119 g of Sn is deposited at the cathode. No substance is lost during the electrolysis. The ratio of the weights ofSnCl2:SnCl4after electrolysis [Atomic weight of Sn = 119]

Options:

Answer:
A
Solution:

2SnCl 2 → SnCl 4  + Sn 2×190   ≡   261    ≡   119 0.38  ≡   0.261    ≡   0.119
When 0.119 g Sn deposited then
(i) SnCl 2 Consumed =0.38 g
SnCl 2 Left =19−0.38 =18.62 g
(ii) SnCl 2 Formed =0.261
W SnCl 2 W SnCl 2 = 18.62 0.261 =71.34:1.
