For the given redox reaction: K(2)Cr(...

For the given redox reaction:
`K_(2)Cr_(2)O_(7) +14HCl to 2KCl +2CrCl_(3) +3Cl_(2) +7H_(2)O`
what is the equivalent mass of HCI? [Given : `M_(HCl) =36.6g//"mol"`]

Text Solution

Verified by Experts

The correct Answer is:
`00085.40`
`K_(2)Cr_(2)O_(7) +14HCl to 2KCl +2CrCl_(3) +3Cl_(2) +7H_(2)O`
Here, the n-factor of `K_(2)Cr_(2)O_(7)=6` and the n-factor of HCl`=(3)/(7)`.
`:.E_(HCl)=(M)/((3)/(7))=(7M)/(3)=85.40`
`=85.40`
