Question

x and y are two electrolytes on dilution molar conductivity of X increases 2.5 times while that of Y increases 25 times which of the two is the weak electrolyte and why​

Answer 1

Explanation:

Y is the weak electrolyte .On dilution,occurs complete dissociation of weak electrolyte and thus steap increase in molar conductivity. However in case of strong electrolyte it has already dissociated ions completely therefore on dilution the rise in conductivity is not very much.

Answer 2

The compound named "Y" is a weak electrolyte.

• The rise or decrease in molar conductivity with dilution can be used to determine the nature of an electrolyte.
• Strong electrolytes totally dissociate when exposed to water. This is because molar conductivity is determined by the number of dissociated ions. There is only a slight increase in bond breakage after dilution, although the number of ions remains the same, hence there is no significant decrease in molar conductivity (2.5 times increased).
• Weak electrolytes do not entirely dissociate. As a result of the dilution, dissociation of ions takes place and the number of ions increases, resulting in a large increase in molar concentration (25 times increased).
• As a result, "X" is a strong electrolyte and "Y" is a weak electrolyte.
