CBSEENCH12010833

The equivalent conductances of two strong electrolytes at infinite dilution in H2O (where ions move freely through a solution) at 25°C are given below:
straight capital lambda subscript CH subscript 3 COONa end subscript superscript straight o space equals space 91.0 space straight S space cm squared divided by equiv
straight capital lambda subscript HCl superscript straight o space equals space 426.2 space cm squared divided by equiv
What additional information/quantity one needs to calculate Λ of an aqueous solution of acetic acid?

  • ∧° of NaCl

  • Λº of CH3COOH

  • The limiting equivalent conductance of  straight H to the power of plus space left parenthesis straight capital lambda subscript straight H to the power of plus end subscript superscript straight o right parenthesis

  • ∧º of chloroacetic acid (C/CH2COOH)

Solution

A.

∧° of NaCl
