Final answer:

Potentiometric titration offers higher precision and can be used with colored solutions, but it requires sophisticated equipment and skilled interpretation. Conversely, titrations with chemical indicators are more straightforward but less precise and not ideal for colored solutions. The correct answer is option c.

Step-by-step explanation:

The question asks to list the advantages and disadvantages of potentiometric titration as compared to titration using chemical indicators. The main advantages of potentiometric titration include the ability to provide more accurate and precise measurements, as it doesn't rely on the human eye to detect color change. Also, it is useful in colored or opaque solutions where visual detection of the end point would be difficult. The technique can be automated and is therefore suitable for handling a large number of samples.

On the other hand, the disadvantages involve a need for more sophisticated, often more expensive equipment, as well as calibration and maintenance of electrodes. It also requires a higher level of training and understanding to interpret the potentiometric data correctly. Additionally, interferences from other redox-active species in the solution can complicate the interpretation of the titration curve.
