what is molar conductivity and how it is related to concentration
Answers
Answer:
Molar conductivity increases with decrease in concentration as the total volume, V, of a solution containing one mole of electrolyte also increases. Upon dilution, the concentration decreases. When the concentration approaches zero, the molar conductivity of the solution is known as limiting molar conductivity, Ë°m.
Solution Concentration. The more concentrated a solution is, the higher the conductivity is. In most cases it is a proportional relationship. As the ion concentration increases, the conductivity increases.
Answer:
The molar conductivity of an electrolyte solution is defined as its conductivity divided by its molar concentration.
where:
κ is the measured conductivity (formerly known as specific conductance)
c is the molar concentration of the electrolyte.
The SI unit of molar conductivity is Siemens metre-squared per mole (S m2 mol-1).[2] However, values are often quoted in S cm2 mol-1.[4] In these last units, the value of molar conductivity may be understood as the conductance of a volume of solution between parallel plate electrodes one centimeter apart and of sufficient area so that the solution contains exactly one mole of electrolyte.
