A Correct answer
Explanation

The Nernst equation is an equation that relates the electrode potential to the concentration of the analyte.

Multiple choice

What is the difference between a potentiometric and a conductometric titration?

  1. In a potentiometric titration, the equivalence point is determined by measuring the change in electrode potential, while in a conductometric titration, the equivalence point is determined by measuring the change in conductivity.

  2. Potentiometric titrations are more sensitive than conductometric titrations.

  3. Conductometric titrations are more versatile than potentiometric titrations.

  4. All of the above.

D Correct answer
Explanation

In a potentiometric titration, the equivalence point is determined by measuring the change in electrode potential, while in a conductometric titration, the equivalence point is determined by measuring the change in conductivity. Potentiometric titrations are more sensitive than conductometric titrations. Conductometric titrations are more versatile than potentiometric titrations.
