HardChemistryFaraday's Law
+4 / -1
Salts of A (atomic mass 15), B (atomic mass 27) and C (atomic mass 48) were electrolysed using same amount of charge. When 4.5 g of A was deposited, masses of B and C deposited were 2.7 g and 9.6 g. The valencies of A, B and C respectively are-
A
1, 3 and 2
B
3, 1 and 3
C
2, 6 and 3
D
