JEE Main 2007 — Electrochemistry Question with Solution
From: AIEEE 2007
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:
= 91.0 S cm2/equiv
= 426.2 S cm2/equiv
What additional information/quantity one needs to calculate of an aqueous solution of acetic acid?
