The equivalent conductance at infinite dilution, $\mathrm{\lambda }°$ of ${\mathrm{NH}}_4\mathrm{Cl}, \mathrm{NaOH}$ and $\mathrm{NaCl}$ are $128.0, 217.8$ and $109.3 {\mathrm{ohm}}^{-1} {\mathrm{cm}}^2 {\mathrm{eq}}^{-1}$, respectively. The equivalent conductance of $0.01 \mathrm{N} {\mathrm{NH}}_4\mathrm{OH}$ is $9.30 {\mathrm{ohm}}^{-1} {\mathrm{cm}}^2 {\mathrm{eq}}^{-1}$. Then the degree of ionization of ${\mathrm{NH}}_4\mathrm{OH}$ at this temperature would be

Blood plasma is maintained at a $\mathrm{pH}$ of $7.4$ largely by the

The variation of equivalent conductance of a weak electrolyte with ${\left(\mathrm{concentration}\right)}^{\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.}$ is represented as

The variation of equivalent conductance of a strong electrolyte with ${\left(\mathrm{concentration}\right)}^{\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$2$}\right.}$ is represented by

The value of molar conductance of $\mathrm{HCl}$ is greater than that of $\mathrm{NaCl}$ at a given temperature and concentration because,

The conductance of $0.1 \mathrm{M} \mathrm{KCl}$(conductivity$=\mathrm{X} {\mathrm{ohm}}^{-1} {\mathrm{cm}}^{-1})$ filled in a conductivity cell is $\mathrm{Y} {\mathrm{ohm}}^{-1}$. If the conductance of $0.1 \mathrm{M} \mathrm{NaOH}$ filled in the same cell is $\mathrm{Z} {\mathrm{ohm}}^{-1}$, the molar conductance of $\mathrm{NaOH}$ will be

In the electrolytic reduction of nitro arene with $50\%$ current efficiency, $20.50 \mathrm{g}$ of the compound is reduced by $2\times 96500 \mathrm{C}$ of electric charge. The molar mass of the compound is

On electrolysing ${\mathrm{K}}_2{\mathrm{SO}}_4$ solution using inert electrodes, $1.68 \mathrm{L} \left(\mathrm{STP}\right)$ of gases were obtained. How many moles of ${\mathrm{MnO}}_4^{-}$ could be reduced to ${\mathrm{Mn}}^{2+}$ by the same quantity of electricity?
