Vedclass · Answer

(D) $(i)$ Conductivity $(\kappa)$ is defined as the conductance of $1 \ cm^3$ of solution. As concentration increases,the number of ions per unit volume increases,so conductivity increases. Thus,statement $(i)$ is False.
$(ii)$ As concentration decreases,the number of ions per unit volume decreases,so conductivity decreases. Thus,statement $(ii)$ is False.
$(iii)$ As temperature increases,the kinetic energy of ions increases and the viscosity of the solvent decreases,which increases the mobility of ions,thereby increasing conductivity. Conversely,if temperature is less,conductivity is less. Thus,statement $(iii)$ is False.
Therefore,all statements are False.

Electrolyte	$\Lambda ^{\infty } (S\ cm^2\ mol^{-1})$
$KCl$	$149.9$
$KNO_3$	$145.0$
$HCl$	$426.2$
$NaOAc$	$91.0$
$NaCl$	$126.5$

Identify True $(T)$ or False $(F)$ for the following statements :
$(i)$ As concentration of solution is more,conductivity is less.
$(ii)$ As concentration of solution is less,conductivity is more.
$(iii)$ As temperature is less,conductivity is more.
