Salts of A (atomic mass 15), B (atomic mass 27) and C (atomic mass 48) were electrolysed using same amount of charge. It was found that when 4.5 g of A was deposited, the mass of B and C deposited were 2.7g and 9.6 g. The valencies of A, B and C respectively.
Text Solution
Verified by ExpertsThe correct answer is:
A
According to Faraday’s second law
= 
= 
= 
= 
0.3n 1 = 0.1n 2 = 0.2n 3 = k
n 1 = 
n 2 = 10k
n 3 = 5k
n 1 : n 2 : n 3 = 
= 
= 2 : 6 : 3
0.3 : 0.1 : 0.2
3 : 1 : 2
