Consider the reaction 1/2H_(2)(g)+AgCI(s)rarrH^(+)(aq)+CI^(-)(aq)+Ag(s) In which of the following galvanic ell the abvoe reaction occurs ?

Answer»

`AG|AgCI(s)|KCI(aq)||AgNO_(3)(Aq)|Ag(s)`
`Pt|H_(2)(g)|HCI(Aq)||AgNO_(3)(aq)||Ag(s)`
`Pt|H_(2)(g)|HCI(aq)||AgCI(s)||Ag(s)`
`Pt|H_(2)(g)|KCI(aq)||AgCI(s)||Ag(s)`

Solution :`H_(2)`UNDERGOES oxidation and `AgCI(ag^(+)`
undergoesreduction therefore cell MAYBE represent as
`Pt|H_(2)(g)|HCI(aq)||AgCI(s)||Ag(s)`
