Question
The equivalent conductances of two strong electrolytes at infinite dilution in H2O (where ions move freely through a solution) at 25oC are given below:
∧oCH3COONa = 91.0 S cm2 / equiv
∧oHCl 426.2 S cm2 / equiv
What additional information/quantity one needs to calculate ∧o of an aqueous solution of acetic acid?
∧oCH3COONa = 91.0 S cm2 / equiv
∧oHCl 426.2 S cm2 / equiv
What additional information/quantity one needs to calculate ∧o of an aqueous solution of acetic acid?
Options
A.∧o of NaCl
B.∧o of CH3COOK
C.The limiting equivalent conductance of H+ (∧oH+)
D.∧o of chloroacetic acid (C/CH2COOH)
Solution
From Kohlrausch′s law
Hence, (1) is the correct answer.
