Lecture 6

Question 1

True or false
When a potential is applied across two electrodes immersed in the solution, the ion and its atmosphere move in opposite directions.

Answer 1

True

Question 2

Conductance of a solution increases with what?

Answer 2

increase in the number of solute molecules/ions, dilution

Question 3

Limiting molar conductivity (Λ∞) is the molar conductivity (Λ) at infinite dilution.

As the solution dilution increases towards infinite dilution what happens to the molar conductivity

Answer 3

Increases

Question 4

Limiting molar conductivity (Λ∞) is the molar conductivity (Λ) at infinite dilution.

What happens to the concentration

Answer 4

Decreases

Question 5

True or false
The electrophoretic effect speeds up the motion of ions within a solution.

Answer 5

False
