Uses of Pt Counter Electrode and Calomel Electrode

 

In some electrochemical cells, there is a constitution of pt counter electrode which plays an important role in the electrochemical reaction. These electrodes are available at a reasonable price in the market and being resistant to acids, oxidation, and other solvents; these are used in varied industries. A counter electrode in used to provide an input potential to a working electrode. It is with their assistance, that the circuit is complete and current keeps flowing continuously through it.

Other than this, there is another type that is very widely used in making of an electrochemical cell. This electrode is named as calomel electrode. As they too are available at a low cost, these are generally used in studying corrosion. There are two electrodes in a cell; the positive is called cathode and anode is the negatively charged electrode. A calomel electrode can be used as a cathode or an anode, depending upon the charge of the other electrode of the cell. They normally function as reference electrodes and the combination of mercury chloride (calomel) and elemental mercury act as the base in these electrodes. You can see their usage in voltmeters and PH meters manufacturing units. They are quite strong in nature and are used in two-electrode systems having a non-reactive chloride salt solvent.

One can get them from sellers that are available online, or by directly contacting with their manufacturers. Nowadays these electrodes are purchased online by reaching to the market’s best names. One can reach to their websites using the internet and can read the reviews section, to get an idea about their reputation. It is important to do the research before placing the order.
