A galvanic cell is composed of two hydrogen electrodes, one of which is a standard one. In which of the following solutions should the other electrode be immersed to get maximum e. m. f.?

View answer and explanation

Correct option: D

0.1M{\kern 1pt} {H_2}S{O_4}

Option D (

0.1M{\kern 1pt} {H_2}S{O_4}

) is correct because it will produce the highest concentration of H+ ions, leading to the largest potential difference compared to the standard hydrogen electrode.
