∧C2 H5 COOH =AC2 H 5 COONa +∧ HCl -∧ NaCl =91.0+426.16-126.45=390.71 ohm -1

Q. Equivalent conductance of $N a Cl, H Cl$ and $C_{2} H_{5} COON a$ at infinete dilution are $126.45, 426.16$ and $91 Ω^{- 1} c m^{2}$ , respectively. The equivalent conductance of $C_{2} H_{5} COO H$ is

$201.28 Ω^{- 1} c m^{2}$

$390.71 Ω^{- 1} c m^{2}$

$698.28 Ω^{- 1} c m^{2}$

$540.48 Ω^{- 1} c m^{2}$

$\land_{C_{2} H_{5} COO H} = A_{C_{2} H_{5} COON a} + \land_{H Cl} - \land_{N a Cl}$
$= 91.0 + 426.16 - 126.45 = 390.71 o h m^{- 1}$
