What is molar conductivity and what is molar conductance ? What is the difference between both terms,?
The resistance of any conductor varies directly as its length (l) and inversely as its cross-sectional area (A), i.eMathematically Where ? is called the specific resistance.l/A is known as cell constant.If l = 1 cm and A = 1 cm2, thenR = ? The specific resistance is, thus defined as the resistance of one centimeter cube of a conductor.The reciprocal of specific resistance is termed the specific conductance or it is the conductance of one centimeter cube of a conductor.It is denoted by the symbo (kappa)l .Thus, Where kappa ? the specific conductance Specific conductance is also called conductivity.Further,or Specific conductance = Conductance × cell constantIn the case of electrolytic solutions, the specific conductance is defined as the conductance of a solution of definite dilution enclosed in a cell having two electrodes of unit area separated by one centimeter apart.Unit of specific conductance:
Where ? is called the specific resistance.
l/A is known as cell constant.
If l = 1 cm and A = 1 cm2, then
R = ?
The specific resistance is, thus defined as the resistance of one centimeter cube of a conductor.
The reciprocal of specific resistance is termed the specific conductance or it is the conductance of one centimeter cube of a conductor.
It is denoted by the symbo (kappa)l .
Thus,
Where kappa ? the specific conductance
Specific conductance is also called conductivity.
Further,
or Specific conductance = Conductance × cell constant
In the case of electrolytic solutions, the specific conductance is defined as the conductance of a solution of definite dilution enclosed in a cell having two electrodes of unit area separated by one centimeter apart.
Unit of specific conductance:
