What is the complete charging reaction of Ni-Cd storage cell ?

Answer»

`Cd_((S))+2Ni(OH)_(4(S)) toCdO_(2(S))+2Ni(OH)_(2)+2H_(2)O_((l))`
`CdO_((S))+NI(OH)_(2(S))+H_(2)O_((l)) to Cd_((S))+2Ni(OH)_(3(S))`
`Cd_((S))+2Ni(OH)_(3(S)) to CdO_((S)) +Ni(OH)_(2(S))+H_(2)O_((l))`
`CdO_(2(S))+2Ni(OH)_(2)+2H_(2)O_((l)) to Cd_((S))+2Ni(OH)_(4(S))`

Solution :`CdO_((S))+Ni(OH)_(2(S))+H_(2)O_((l)) to Cd_((S))+2Ni(OH)_(3(S))`
