Question: The ionic conductance of following cation in a given concentration are in the order [Orissa JEE 2004]
Options:
A) $ L{{i}^{+}}<N{{a}^{+}}>{{K}^{+}}<R{{b}^{+}} $
B) $ L{{i}^{+}}>N{{a}^{+}}>{{K}^{+}}>R{{b}^{+}} $
C) $ L{{i}^{+}}<N{{a}^{+}}>{{K}^{+}}>R{{b}^{+}} $
D) $ L{{i}^{+}}=N{{a}^{+}}<{{K}^{+}}<R{{b}^{+}} $
Show Answer
Answer:
Correct Answer: A
Solution:
With the increase in size of cation the size of the hydrated ion decreases hence ionic conductance increases.
