प्रश्न

Define the following terms: Molar conductivity (m)

उत्तर

 

Molar conductivity (Λm) of a solution at a given concentration is the conductance of the volume V of the solution containing one mole of an electrolyte placed between two electrodes with the cross-sectional area (A) and the distance of unit length (l). Therefore

`^^_m=kA/l`

Since, l = 1 and A = V (volume containing one mole of electrolyte)

 `^^_m=kV`

Molar conductivity of substance “A” is 5.9 × 103 S/m and “B” is 1 × 10–16 S/m. Which of the two is most likely to be copper metal and why?


Given below are two statements:

Statements I: The limiting molar conductivity of KCl (strong electrolyte) is higher compared to that of CH3COOH (weak electrolyte).

Statement II: Molar conductivity decreases with decrease in concentration of electrolyte.
In the light of the above statements, choose the most appropriate answer from the options given below:


Assertion (A): Molar conductivity decreases with increase in concentration.

Reason (R): When concentration approaches zero, the molar conductivity is known as limiting molar conductivity.
