Question

An electrochemical cell is shown below Pt, H 2(1 atm )| HCl (0.1 M)| CH 3 COOH (0.1 M) mid H 2(1 atm ), Pt The EMF of the cell will not be zero, because (A) EMF depends on molarities of acids used (B) pH of 0.1 M HCI and 0.1 M CH3COOH is not same (C) the temperature is constant (D) acids used in two compartments are different

Tardigrade Admin · Accepted Answer

The EMF of the cell will not be zero because concentration of H+ ions in two electrolytic solutions is different. Mean HCl is strong acid where, acetic acid is weak acid and gives different pH.

Q. An electrochemical cell is shown below $Pt$ ,
$H_{2} (1 a t m) ∣ H Cl (0.1 M) ∣ C H_{3} COO H (0.1 M) ∣ H_{2} (1 a t m), Pt$
The EMF of the cell will not be zero, because

EMF depends on molarities of acids used

pH of $0.1 M H C I$ and $0.1 M C H_{3} COO H$ is not same

the temperature is constant

acids used in two compartments are different

The EMF of the cell will not be zero because concentration of $H^{+}$ ions in two electrolytic solutions is different. Mean $H Cl$ is strong acid where, acetic acid is weak acid and gives different $p H$ .
