Question

Check the feasibility of the following redox reaction with the help of electrochemical series
`Ni(s)+2Ag^(+)(aq) to Ni^(2+)(aq)+2Ag(s)`

Answer 1

The `E^(@)` value of `Ni^(2+)//Ni "is" -0.25" V"` while that of `Ag^(+)//Ag is +0.80" V"`. This means that nickel is placed below silver in the series and can easily reduce `Ag^(+)` ions to silver by releasing electrons. The redox reaction is therefore,feasible.
