The button cell used in watches function as follows
`Zn_a + Ag_(2)O(s) + H_2O_((l))

A

0.84 V

B

1.34 V

C

1.10 V

D

0.42 V

Text Solution

Verified by Experts

The correct Answer is:
C
Anodic oxidation: (Reverse the given reaction)
`(E_("ox")^@) = 0.76V ` cathodic reduction
`:. E_("cell")^(@) = (E_("ox")^@) + (E_("Red")^(@)) = 0.76 + 0.34 = 1.1V `.
