What is symbolic representaiton of given following reaction. Fe_((S)) + Cd_((aq))^(2+) hArr Fe_((aq))^(2+)+Cd_((S))

Answer»

`""^(Theta)Fe_((S))|Fe_((1M))^(2+)||Cd_((S))|Cd_((1M))^(2+)o+`
`""^(Theta)Cd_((S))|Cd_((1M))^(2+)||Fe_((1M))^(2+)|Fe_((S))o+`
`""^(Theta)Cd_((S))|Cd_((1M))^(2+)||Fe_((S))|Fe_((1M))^(2+)o+`
`""^(Theta)Fe_((S))|Fe^(2+)(1M)||Cd_((1M))^(2+)|Cd_((S))o+`

Solution :`""^(Theta)Fe_((S))|Fe^(2+)(1M)||Cd_((1M))^(2+)|Cd_((S))o+`
`Fe_((S)) to Fe_((AQ))^(2+)+2e^(-)`Oxidation (Anode)
`Cd_((aq))^(2+)+2e^(-) to Cd_((S))`REDUCTION (Cathode)
`therefore ""^(Theta)Fe_((S))|Fe_((1M))^(2+)||Cd_((1M))^(2+)|Cd_((S))o+`
