In redox reaction, H 2 O 2 oxidises K 4 [ F e ( C N ) 6 ] into K + , F e + 3 , C O 3 - 2 and N O 3 - ions in acidic medium, than how many moles of H 2 O 2 will react with 1 m o l e of K 4 [ F e ( C N ) 6 ]

Question

In redox reaction, H 2 O 2 oxidises K 4 [ F e ( C N ) 6 ] into K + , F e + 3 , C O 3 - 2 and N O 3 - ions in acidic medium, than how many moles of H 2 O 2 will react with 1 m o l e of K 4 [ F e ( C N ) 6 ], 5 m o l e s, 9 m o l e s, 8 m o l e s, 30.5 m o l e s

n - f a c t o r o f H 2 O 2 = 2 n - f a c t o r of K 4 [ F e ( C N ) 6 ] = 61 ∵ m o l e o f H 2 O 2 1 m o l e o f K 4 F e ( C N ) 6 = 61 2 ∴ m o l e of H 2 O 2 = 61 2 × 1 = 30.5
