The raction , `K_(2)Cr_(2)O_(7)+mFeSO_(4)rarrnH_(2)SO_(4)rarrCr_(2)(SO_(4))_(3)+pFe_(2)(SO_(4))_(3)+qH_(2)O` when balanced, m,n,p and q are respectively :

A

6,14,3,14

B

6,7,3,7

C

3,7,2,7

D

4,14,2,14

Text Solution

Verified by Experts

The correct Answer is:
B
`1K_(2)overset((+6))(Cr_(2))O_(7)+6overset((+2))(FeSO_(4))+7H_(2)SO_(4)rarr1overset((+3))(Cr_(2))(SO_(4))_(3)+3overset((+3))(Fe_(2))(SO_(4))_(3)+1K_(2)SO_(4)+7H_(2)O`

`(3xx2)=6(1xx1)=1`
i.e., answer is m=6,n=7,p=3,q=7
