# How do you convert a reference electrode?

## How do you convert a reference electrode?

1. The general equation for this conversion at any pH using Ag/AgCl reference electrode is:
2. E(RHE) = EAg/AgCl + 0.059 pH + EoAg/AgCl.
3. Where EoAg/AgCl = 0.1976 V at 25oC and E Ag/AgCl is your working potential.

How do you convert NHE to rhe?

Normal hydrogen electrode (NHE) (E ≈ 0.000 V) concentration H+ = 1 Molar. Reversible hydrogen electrode (RHE) (E = 0.000 V – 0.0591 × pH)

### Which of the following is a reference electrode?

The most commonly used reference electrode is calomel electrode.

Is she and NHE same?

Technically, a SHE and NHE are different. The NHE measures the potential of a platinum electrode in a 1 N acid solution, while the SHE measures the potential of a platinum electrode in an ideal solution (current standard of zero potential at all temperatures).

#### What is V vs NHE?

The difference in potential between the Normal Hydrogen Electrode (NHE) and the Standard Hydrogen Electrode (SHE) is 0.006 V,1,2 which stems from using 1 N solvated H+ vs unit activity of solvated H+.

What makes a good reference electrode?

Everyone agrees that an ideal reference electrode has a stable, well-defined electrochemical potential. An ideal reference electrode should also have zero impedance. As discussed below, a reference electrode’s impedance can strongly affect the performance of a potentiostat.

## What is the best reference electrode for corrosion studies?

In corrosion studies, the most popular reference electrodes are: 1 Saturated calomel electrode (SCE), 2 Silver-silver chloride (SSC) saturated, 3 Copper-copper sulfate (CCS), and 4 Saturated mercury-mercurous sulfate (MMS). More

How to measure electrode potentials?

The measurement of electrode potentials requires the use of a reference electrode. Reference electrodes must exhibit a stable potential value under the specified polarization conditions; in electrochemistry terms, they must behave as ideally non-polarizable electrodes.

### Why do we use equation pairs in electrodes?

Electrode potentials always have to indicate the reference electrode against which they were measured. Lastly, the use of equation pairs allows the development of spreadsheets or applications to automate reference electrode scale conversions. Such as this one developed by my son Lorenzo.

What do the corrosion doctors’visitors learn?

The Corrosion Doctors’visitors are also surprised when they learn that these corrosion processes may also be happening inside their own body !! However, the topics covered in the many pages of the Web site go much beyond metallic corrosion because what is corrosion after all? a daily annoyance?
