Consider the following Galvanic cell:-

By what value the cell voltage when concentration of ions in anodic and cathodic compartments both increased by factor of 10 at 298K:

A

`+0.0591`

B

`-0.0591`

C

`-0.1182`

D

0

Text Solution

Verified by Experts

The correct Answer is:
C
`{:("Anode":, H_(2) rarr 2H^(+) +2e^(-)),("Cathode":,CI_(2)+2e^(-) rarr 2CI^(-)):}`
`E = E^(@) - 0.0591 log [H^(+)] [CI^(-)]`
on increasing concentration by 10 E wil increase by a factor of `-0.0591log 100 =- 0.0591 xx 2`
`=- 0.1182 V`

Accidentally chewing on a stray fragmet of aluminium foil can causes a sharp tooth path if the aluminium comes in contact with an amalgam filing. The filing, an alloy of silver, tin and mercury, acts as the cathode of a tiny galvanic cell, the aluminium behaves as the anode, and salivas serves as the electrolyte. when the aluminium and the filling come in contact, and electric current passage from the aluminium to the filling which is sensed by a nerve in the tooth. Aluminium is oxidized at the anode, and O_(2) gas is reduced to water at the cathode.
