एनोड पर सेल अभिक्रिया --- `Mg_((s))toMg^(2+)(0*001M)+2e^(-)`
केथोड अभिक्रिया --- `Cu^(2+)(0*0001M)+2e^(-)to Cu_((s))`
नेट सेल अभिक्रिया --- `Mg_((s))+Cu^(2+)(0*0001M)toMg^(2+)(0*001M)+Cu_((s))`
नरंसत समिकरारन के अनुसार,
`EMF=E_("cell")^@-(0*591)/2"log"([Mg^(2+)])/([Cu^(2+)])`
`rArr" "EMF=E_(Cu^(2+)//Cu)^2-E_(MG^(2+)//Mg)^@`
`-(0*591)/2"log"(0*001)/(0*0001)`
`={0*34V-(-2*307)}-0*0295Vxxlog 10`
`:." "EMF=(2*71-0*0295)`
`V=2*68 V`.
