Embibe Experts Solutions for Chapter: Electrochemistry, Exercise 2: Exercise-2

A hỷrogen electrode placed in a buffer solution of ${\mathrm{CH}}_3\mathrm{COONa}$ and acetic acid in the ratios $\mathrm{x}:\mathrm{y}$ and $\mathrm{y}:\mathrm{s}$ has electrode potential values ${\mathrm{E}}_1$ volt and ${\mathrm{E}}_2$ volt respectively at ${25}^0\mathrm{C}$. The $\mathrm{pKa}$ value of acetic acid is (${\mathrm{E}}_1$ and ${\mathrm{E}}_2$ are oxidation potential)

When electric current is passed through a cell having an electrolyte, the positive ions move towards the cathode and the negative ions towards the anode. If the cathode is pulled out of the solution_______.

A current of $2.68 \mathrm{A}$ is passed for one hour through an aqueous solution of $\mathrm{CuSO},$ using copper electrodes. Select the correct statement(s) from the following:

Mark out the correct statement(s) regarding electrolytic molar conductivity.

On increasing dilution following will increase:

The resistances of following solutions of $\mathrm{KCl}$ were measured using conductivity cells of different cell constants, at same temperature. (Consider that at concentration less than $0.1 \mathrm{M}$ , the specific conductivity of solution is directly proportional to the concentration of solution.) 

$\begin{array}{|lll|}\hline & \text{ Concentration of Solution }& \text{ Cell Constant }\\ 1.& 0.1\mathrm{M}& 1{\mathrm{cm}}^{-1}\\ 2.& 0.01\mathrm{M}& 10{\mathrm{cm}}^{-1}\\ 3.& 0.005\mathrm{M}& 5{\mathrm{cm}}^{-1}\\ 4.& 0.0025\mathrm{M}& 25{\mathrm{cm}}^{-1}\\ \hline\end{array}$
