20. Equivalent conductance of NaCl, HCI and
CH3COONa at infinite dilution are 126.45, 425.16 and
91ohm-1 cm2 respectively. The equivalent
conductance of CH2COOH at infinite dilution would
be
(1) 101.38 ohm-7 cm2 (2) 253.62 ohm-7 cm?
(3) 389.71 ohm-1 cm2 (4) 678.90 ohm-1 cm2

Answer:
Option 3 is correct
Explanation:
As, CH3COOH + NaCl = CH3COONa + HCl
Hence,
λ eq(CH3 COOH)∞ =λ eq(CH 3 COONa)∞ +λ eq(HCl)∞ −λ eq(NaCl)
= 91 + 425.16 - 126.45
= 389.71
