Question

Solutions of two electrolytes A and B are diluted. The limiting molar conductivity of B increases to a smaller extent while that of A increases to a much larger extent comparatively. Which of the two is a strong electrolyte? Justify your answer.

Answer 1

Answer:solution B is the strong electrolyte.

- because, for strong electrolytes molar conductivity increases with dilution and reaches a certain limiting value as the concentration approaches to zero

-and for weak electrolyte, molar conductivity increases rapidly with dilution and no limiting value is reached

Explanation:

Answer 2

"B" is strong electrolyte than compared to "A" electrolyte.

Step by step explanation:

• The molar conductivity nature of weak and strong electrolytes are completely depends on their dilution.
• But it is little more increases the molar conductivity for weak electrolytes on their dilution than compared to the strong electrolyte.
• From the given data , the increasing of molar conductivity is less for B and more for "A" than "B".
• Therefore,"A" is weak electrolyte and "B" is strong electrolyte.
