Question

Define conductance,specific conductance,molar conductance and equivalent conductance?

Answer 1

Explanation:

the degree to which an object conducts electricity, calculated as the ratio of the current which flows to the potential difference present. This is the reciprocal of the resistance, and is measured in siemens or mhos is called conductance.

Conductivity of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is Siemens per meter is specific conductance.

The molar conductivity of an electrolyte solution is defined as its conductivity divided by its molar concentration. {\displaystyle \Lambda _{\text{m}}={\frac {\kappa }{c}}, } where: κ is the measured conductivity, c is the molar concentration of the electrolyte.

The equivalent conductance of an electrolyte is defined as the conductance of a volume of solution containing one equivalent weight of dissolved substance when placed between two parallel electrodes 1 cm apart, and large enough to contain between them all of the solution.
