Standard zinc electrode is coupled with a standard electrode to form a cell, whise emf was found to be 1.60V , reduction taking place at Zinc electrode . If standard reduction potential of zinc electrode is -0.76V, then the standard reduction potential of the standard electrode will be______ V.

Answer»

`-2.36`
`+0.84`
2.36
`-0.84`

Solution :`{:(1.6=-0.76 + (-X) therefore x =-2.36),([E_("CELL")^(0) = E_("Zn(red)")""+(-E_("electrode")^(0))]):}`
