Solutions of two electrolytes A and B are diluted. The `Lambda_(m)` of 'B' increases 1.5 times while that of A increases 25 times. Which of the two is a strong electrolyte? Justify your answer.

Text Solution

Verified by Experts

B' is a strong electrolyte because of dilution of a strong electrolyte, number of ions remains the same. Only interionic attraction decreases and therefore increase in `wedge_(m)` is small.
