Question

Calculate ∧[infinity] HOAc
L¥ using appropriate molar conductances of
the electrolytes listed above at infinite dilution in H₂O at
25°C
(a) 217.5 (b) 390.7
(c) 552.7 (d) 517.2

Answer 1

The conductance of the electrolytes listed above at infinite dilution in H₂O at  25°C is HOAc ∞ =  390.7 S cm^2  mol  −1

Option (B) is correct.

Explanation:

HCl + NaOAc ⟶ NaCl + HOAc

Now

HOAc ∞  = Δ NaOAc∞  + ΔHCl ∞  − Δ NaCl ∞

HOAc ∞ = (91.0 + 426.2 − 126.5) S cm^2  mol  −1

HOAc ∞ = 390.7 S cm^2  mol  −1

Thus the conductance of the electrolytes listed above at infinite dilution in H₂O at  25°C is HOAc ∞ =  390.7 S cm^2  mol  −1.
