What Is Molar Conductivity?
Molar conductivity, (位), is the magnitude of a solution that contains one mole of dissolved matter per liter volume. It is measured in Siemens per m or cm (S/m). Molar conductivity is a measure of the migrating ability of the molecules in solution due to an applied electric field.
Experimentally, the molar conductivity is evaluated by doing a measurement of conductance in a solution through the use of an instrument known as the conduction meter and subsequently dividing it by concentration which has been measured for that particular solution mol/L. Mathematically, it is given by the equation:
位 = 魏 / c
- 位 is Molar Conductivity
- 魏 represents a solution in S/cm
- c is Concentration of Solute
Variation of Molar Conductivity with Concentration
Molar Conductivity of various electrolytes is shown in the image added below,
Molar conductivity of both weak and strong electrolytes increases with a decrease in concentration or dilution.
Molar Conductivity
Molar Conductivity is a basic physical chemistry concept that greatly impacts the understanding of electrical conduction in electrolyte solutions. This parameter denoted by the symbol 螞m sheds light on this ion鈥檚 ability to transport current in solution. With the concentration of ions and their mobility, molar conductivity is a criterion for clarifying electrolyte behavior. Molar conductivity is important topic in class 12 Electrochemistry.
