Redox Reactions And Electrochemistry Ques 574
Question: The ionic conductivity of $ B{a^{2+}} $ and $ C{l^{-}} $ at infinite dilution are 127 and 76 $ oh{m^{-1}} $ $ cm^{2}e{q^{-1}} $ respectively. The equivalent conductivity of $ BaCl_2 $ at infinity dilution (in $ oh{m^{-1}},Cm^{2}e{q^{-1}} $ ) would be:
Options:
A) 203
B) 279
C) 101.5
D) 139.5
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Equivalent conductivity of $ BaCl_2 $ $ \Lambda _m^{\infty }(BaCl_2)=\lambda _m^{\infty }(B{a^{2+}})+2\lambda _m^{\infty }(C{l^{-}}) $ $ =127+2\times 76=279oh{m^{-1}}cm^{2}e{q^{-1}}. $
