Which element is the reference element is chemistry?
Carbon is the reference element for the definition of the mole. In electrochemistry, the reference element/electrode is the Hydrogen electrode and all electrode potentials are against the hydrogen standard.
What is mean by law hydrogen electrode?
Low Hydrogen? It is a welding electrode that has controlled Hydrogen levels for use in SMAW i.e E7018. Not to be confused with a low hydrogen processes like GMAW and GTAW
Why is standard hydrogen electrode called reversible electrode?
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
How are standard electrode potentials determined for the half-cells listed in the Standard Reduction Potentials table?
The standard electrode potentials are determined on the basis of the Hydrogen scale.The standard electrode potential of Hydrogen is arbitrarily fixed as zero.
Why is platinum coated with platinum black used in the standard hydrogen electrode?
The platinum black provides a very high surface area that promotes the speed of reaction at the electrode and thereby virtually eliminates overpotential at the standard hydrogen electrode. An overpotential would lead to misleading values of potential of other electrodes compared with a standard hydrogen electrode that manifested overpotential.
What are the Types of ion selective electrodes?
glass electrode, antimony electrode, the hydrogen electrode
What is standard hydrogen electrode?
Standard hydrogen electrode forms the basis of the thermodynamic scale of oxidation reduction potentials.
What is difference between standard hydrogen electrode and normal hydrogen electrode?
E(SCE)-E(H)=241 mV @25°C SHE is a primary standard electrode bt SCE is secondary reference electrode use for more easier work than SHE & SCE,s potential also measured by taking SHE as reference electrode.

How do you separate the hydrogen from the oxygen in water?
You pass an electrical current through the water. The positive electrode will release oxygen while the negative electrode will release hydrogen.
How are standard electrode potentials determined for the half-cells listed in the Standard Reduction Potentials table?
The standard electrode potentials are determined on the basis of the Hydrogen scale.The standard electrode potential of Hydrogen is arbitrarily fixed as zero.
Which electrode is used for welding of MS to SS?
We were told 309 was the electrode of choice.
How to calculate hydrogen electrode?
By doing the Nernst equation
What is the full form of NHE?
Normal Hydrogen Electrode
Why is platinum coated with platinum black used in the standard hydrogen electrode?
The platinum black provides a very high surface area that promotes the speed of reaction at the electrode and thereby virtually eliminates overpotential at the standard hydrogen electrode.
