Electrochemical testing - 2 - What is a reference electrode?

What is a reference electrode?

A reference electrode is used as a scale to measure the potential of the working electrode.

Reversible reactions

Just as a scale is unchanging, the potential and chemical conditions of the reference electrode should also be unchanging.

Thus, it is necessary that the reactions - oxidation and reduction - occurring inside a reference electrode are reversible. This ensures constant chemistry.

No polarization

It also ensures that there is no net polarization as both reactions occur simultaneously at different points in the reference electrode. this keeps its potential constant.

Thus, the potential of any working electrode connected to this reference electrode will be dependent only on the conditions of the working electrode. This makes it easier to note the changes happening in the working electrode.

What is a Corrosion Loop - PART 2 - EXAMPLE

How to prepare a corrosion loop? To prepare a corrosion loop, the person in charge will look at the overall picture and answer the following questions - 1. What is the process? 2. What are the components? 3. What are the materials for each component? 4. What are the common features among them? 5. Where does the commonality end? - This is important as that will mark the beginning of a new corrosion loop. 6. Can I use the same inspection procedure for all of them? 7. Do they corrode/get damaged in the same manner due to the same reasons? WATCH THE VIDEO FOR A DETAILED EXPLANATION - Read part 1 here! https://corrospective.com/ 😀Happy learning! 😀

How many pages long should my research paper/thesis be?

In this post, I would like to address an issue that is encountered by many undergraduates and postgraduates who are doing their very first research project. In my experience of designing and managing projects for undergraduates, interns, and postgraduates, I so often get asked two questions - 1) "How many pages should my research report/thesis/paper be?" 2)"How many references should I put at the end of the paper?" My answer is stop focusing on the number unless it is a strict requirement. Base your report on what you have learnt in the research work. Concentrate on describing the amazing new things that you have got acquainted with. At each step of the project, you will come across a small question leading to reading of new references, and you will not need to find more just for the sake of it. Enjoy the process of writing something you found amazing. Check out the detailed video below! FREE RESEARCH CHECKLIST TEMPLATE AVAI...

Electrochemical testing - 1 - Potentiostat

explanation Potentiostat is an instrument to measure as well as apply potential and current. It includes a voltmeter and an ammeter. The voltmeter may also be called an electrometer. It is connected between the working and the reference electrode. Its main function is to measure the potential of the working electrode. It is a crucial component because all the experiments require an accurate measurement of the potential to determine their further potential or current variation.
