Question

Define the following terms:
(i) Molar conductivity $(\bigwedge m)$
(ii) Secondary batteries

Answer 1

Molar conductivity (${\Lambda }_m$):-

Molar conductivityis defined as the conductivityof an electrolyte solution divided by the molar concentrationof the electrolyte and so measures the efficiency with which a given electrolyte conducts electricity in solution. It is the conducting power of all the ions produced by dissolving one mole of an electrolyte in solution. The usual symbol is a capital lambda, $\Lambda ,{\Lambda }_m$.

Secondary batteries

A rechargeable battery, storage battery, secondary cell, or accumulator is a type of electrical battery which can be charged, discharged into a load and recharged many times, while a non-rechargeable or primary battery is supplied fully charged and discarded once discharged.
