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.

Options

A. `-2.36`
B. `+0.84`
C. 2.36
D. `-0.84`

Answer

A

Explanation

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