Which of the following measurements can be made by the measurement of emf ?
Correct answer: D. All A., B. & C.
- A. pH value
- B. Degree of hydrolysis
- C. Composition of complex ions
- D. All A., B. & C.
Explanation
Potentiometric emf measurements can be used to determine pH and, through suitable equilibrium-cell measurements, hydrolysis and complex-ion composition. Hence all three listed applications are possible.
