Assertion `(A) :` In a Daniell cell, if the concentration of `Cu^(2+)` and `Zn^(2+)` ions are doubled, the `EMF` of the cell will be doubled.
Reason `(R) :` If the concentration of ions in contact with metals is doubled, the electrode potential is doubled.

Text Solution

Verified by Experts

c : Correct reason : Emf of a cell depends upon the concentration the concentration of both `Zn^(2+)` and `Cu^(2+)` ions , e.m.f. remains the same .
`E = E^(@) - (RT)/(nF) ""ln ([Zn^(2+)])/([Cu^(2+)])`
