Redox Reactions And Electrochemistry Question 488
Question: The equivalent conductance at infinite dilution of a weak acid such as HF
Options:
A) can be determined by extrapolation of measurements of dilute solutions of $ HCl,HBr $ and HI
B) can be determined by measurement of very dilute HF solutions
C) can be determined from measurements of dilute solutions of $ NaF,NaCl $ and $ HCl $
D) is an undefined quantity
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Kohlrausch Law, $ {\Lambda_{eq}}( NaF )+{\Lambda_{eq}}( HCl )- $ $ {\Lambda_{eq}}(NaCl)={\Lambda_{eq}}(HF) $
