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.
The normal hydrogen electrode (NHE) consist of immersing a platinum electrode into a solution of 1N acid solution (usually achieved by bubbling hydrogen gas through the solution at 1 atm). The standard hydrogen electrode (SHE) is the potential of a platinum electrode in a theoretical solution of H+ is 1 mol/L.
They are the same chemical.
There should be much electro negativity difference to form H bond.There is no enough difference between H and S.
A hydrogen atom is made from 1 hydrogen atom while a hydrogen molecule is made by 2 hydrogen atoms in a chemical compound thus making it twice as big too.
The prefix di- means two, dihydrogen means there are two hydrogen atoms, as opposed to a single one.
H2 is molecular hydrogen. H2S is hydrogen sulfide and is extremely toxic.
Often electrochemical studies are interested in one of the electrodes of the cell only. The second electrode is present to complete the cell. Electrode of interest is named working electrode or the indicator electrode; the second electrode is know as reference electrode or auxiliary electrode (counter electrode).
It consists of tube in the bottom of which is a layer of mercury ,over which is placed a paste of Hg+HgCl2.The remaining portion of cell is filled with a solution of normal or decinormal or saturated solution of KCl. a platinum wire dipping into the mercury layer is used for making electrical contact. the side tube is used for electrode is formulated as;Hg,Hg2Cl2,KCl. the electrode can be coupled with the hydrogen electrode of unknown pH.
If electrons are left behind in metal this will increase the voltage difference between a metal electrode and a solution. Also if the solution becomes more positive this will cause an increase.
Monopolar electrode is single electrode measure voltage with respect to grond ,but bipolar electrode is two electrode measures the diff. voltage mainly bipolar is used inorder to get high Signal to Noise ratio.
The difference between a hydrogen atom and atomic hydrogen is that the "hydrogen atom" represents one atom of the chemical element hydrogen. Atomic hydrogen are isolated hydrogen atoms.
What is the difference between standard theory and extended standard theory?
the difference is that standard is being used by majority
They are the same chemical.
The difference between actual quantity and standard quantity is called the material quantity variance.
1 more neutron
Hydrogen is an element, the electron is a subatomic particle.
The difference is the amount of hydrogen and oxygen
