Question

Equivalent conductance at infinite dilution for weak electrolyte HF:

• A. can be determined by measurement of equivalent conductance at infinite dilution for dilute solution of $HCL,HBr$ and $HI$
• B. can be determined by measurement of equivalent conductance at infinite dilution for very dilute $HF$ solutions
• C. can best be determined from measurements on dilute
• D. can not be calculated

Answer 1

The correct option is B can be determined by measurement of equivalent conductance at infinite dilution for very dilute $HF$ solutions

For weak electrolytes, equivalent conductance at infinite dilution can be determined by their very dilute solutions. Hence, for $HF$. equivalent conductance at infinite dilution can be determined by measurements of very dilute $HF$ solutions.
