A) 39%
B) 3.9%
C) 0.35%
D) 0.039%
Correct Answer: B
Solution :
We know \[\lambda _{{{C}_{6}}{{H}_{5}}COOH}^{\infty }=\lambda _{{{C}_{6}}{{H}_{5}}CO{{O}^{-}}}^{\infty }+\lambda _{{{H}^{+}}}^{\infty }\] \[=42+288.42\] \[=330.0.42\] Degree of dissociation\[\alpha =\frac{{{\lambda }_{v}}}{{{\lambda }_{\infty }}}=\frac{12.8}{330.42}\] \[=0.039\times 100\] \[=3.9%\]You need to login to perform this action.
