Question
pH meter is an example ofa) amperometric biosensorb) conductive biosensorc) potentiometric biosensord) piezo electric biosensor
Solution
A pH meter is an example of a potentiometric biosensor.
Here's a step-by-step explanation:
-
A pH meter measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH.
-
The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode.
-
This difference in electrical potential relates to the potentiometric measurement principle.
-
Therefore, a pH meter falls under the category of potentiometric biosensors.
So, the correct answer is c) potentiometric biosensor.
