330023 The highest electrical conductivity of the following aqueous solutions is of:

1 0.1 M difluoroacetic acid
2 0.1 M chloroacetic acid
3 0.1 M acetic acid
4 0.1 M fluoroacetic acid
CHXII03:ELECTROCHEMISTRY

330024 Assertion :
The electrical resistance of a column of \({\text{0}}{\text{.05}}\,\,{\text{M NaOH}}\) solution of diameter \(1 \mathrm{~cm}\) and length \(50 \mathrm{~cm}\) is \(5.55 \times 10^{3} \mathrm{ohm}\). Its resistivity is equal to \(76.234 \Omega \mathrm{Cm}\).
Reason :
Resistivity directly propotional to \(\left( {\frac{{\text{A}}}{{\text{I}}}} \right)\).
