Question

Unit of ionic mobility is

• A. $m^2sec^{-1}volt$
• B. $ms^{-1}$
• C. $m sec^{-1}$ volt
• D. $m sec^{-1} volt^{-1}$

Answer 1

Answer: (A)

$m^2sec^{-1}volt$

Answer 2

The ionic mobility $(\mu)$ is defined as the velocity attained by an ion moving through a gas under unit electric field. A suitable unit is therefore $m ^{2} s ^{-1} volt ^{-1}$.
