Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Amperometry detection.
Amperometry measures the electric current produced by electron transfer reactions during redox processes.
Step 2: Potentiometry detection.
Potentiometry detects changes in the potential difference between electrodes and is used to measure the concentration of ions, often via changes in the ionic medium.
Final Answer: \[ \boxed{\text{Amperometry, Potentiometry}} \]
Amperometry measures the electric current produced by electron transfer reactions during redox processes.
Step 2: Potentiometry detection.
Potentiometry detects changes in the potential difference between electrodes and is used to measure the concentration of ions, often via changes in the ionic medium.
Final Answer: \[ \boxed{\text{Amperometry, Potentiometry}} \]
