Question
Solutions of two electrolytes ‘A’ and ‘B’ are diluted. The Λm of ‘B’ increases 1.5 times while that of A increases 25 times. Which of the two is a strong electrolyte? Justify your answer.
Solution
Electrolyte ‘B’ is strong as on dilution the number of ions remains the same, only interionic attraction decreases; therefore, the increase in Λm is small.
