Question

What are the advantages of using a microelectrode for

voltametric measurements?

Short answer

The benefits of microelectrodes in voltammetry techniques has been explained.

Step-by-step solution

Define voltammetry

In the electrochemical reactions the relation between current and voltage is noted and this technique is called voltammetry. A graph which represents current Vs voltage is called voltammogram.

Determine the benefits of microelectrodes in voltammetry techniques

• Microelectrodes can be placed in small places and due to less ohmic loss which is handy in nonaqueous solutions.
• Because of its small capacitance, it allows fast scanning of voltages which allows to the analysis of unstable species.
• It also increases the analyte sensitivity due to low capacitance which provides low current.
