Which of the following will have the highest electrical conductance? A) 0.1 M KCl B) 0.2 M KCl C) 0.1 M CH₃COOH D) 0.2 M CH₃COOH

Question

Quizplus · Accepted Answer

The electrical conductance of a solution depends on the concentration of ions in the solution. KCl is a strong electrolyte, meaning it completely dissociates into its ions (K+ and Cl-) in water. Therefore, a 0.2 M KCl solution will have more ions than a 0.1 M KCl solution, leading to higher electrical conductance. CH₃COOH is a weak acid and will not dissociate completely in water, so both 0.1 M and 0.2 M solutions will have similar conductance values, but they will be lower than the conductance of KCl solutions due to the lack of complete dissociation.
