Conductivity of acetic acid KCl solutions
October 4th, 2022
The conductivity of a 0.1 moldm^-3 solution of potassium chloride at298K was found to be 1.1639 x 10^-2 Scm^-1. In a separate experiment at 298K the resistance of a 0.1 moldm^-3 solution of ethanoic acid was determined as 300 ohms and the resistance of the potassium chloride solution was fond to be 33.21 ohms. Given that the specific conductivity of the water used to prepare the ethanoic acid and potassium chloride solutions was 7.6 x 10^-4 Scm^-1 at 298K, calculate the molar conductivity of the ethanoic acid solution.
(Tip: The conductivity of the solutions comprises the conductivity due to the salt or acid and the conductivity due to dissociated water)
