The standard electrode potentials are determined on the basis of the Hydrogen scale.The standard electrode potential of Hydrogen is arbitrarily fixed as zero.
Standard electrode potentials are listed in the table in decreasing order, with the strongest reducing agents (highest standard reduction potentials) at the top and the strongest oxidizing agents (lowest standard reduction potentials) at the bottom. The potentials are measured relative to the standard hydrogen electrode.
The standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials.
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.
SHE stands for Standard Hydrogen Electrode. It is a reference electrode used in electrochemistry to measure electrode potentials. SHE is assigned a potential of 0 volts at all temperatures.
The primary reference electrode is the hydrogen electrode, which is rather fiddly to work with. Secondary references are chosen for their stability and their reliable potentials so others can be calibrated against them.

The cell potential in a chemical reaction can be determined by calculating the difference in standard electrode potentials of the two half-reactions involved in the cell. The cell potential is the difference between the reduction potentials of the two half-reactions. The formula for calculating cell potential is Ecell Ered(cathode) - Ered(anode).
Hydrogen is used as a standard electrode because it has a well-defined standard electrode potential and is easily reversible in its oxidation and reduction reactions. This makes it a reliable reference point for measuring the electrode potentials of other half-reactions in electrochemical cells.

The standard hydrogen electrode (SHE) is a reference electrode used in electrochemistry to measure electrode potential. It consists of a platinum electrode in contact with a solution of hydrogen ions at unit activity and surrounded by hydrogen gas at a pressure of 1 bar. The SHE has an assigned potential of 0 V at all temperatures.
The primary reference electrode is the hydrogen electrode, which is rather fiddly to work with. Secondary references are chosen for their stability and their reliable potentials so others can be calibrated against them.
Andre Jacques De Bethune has written: 'Standard aqueous electrode potentials and temperature coefficients at 25'
TTX blocks voltage-gated sodium channels, which are necessary for action potential initiation and propagation. When TTX is applied, sodium influx is prevented, leading to a decrease in action potentials recorded at electrode R2 due to the inability of neurons to generate and transmit action potentials.

The graphite rod acts as the positive terminal because it is the cathode where reduction reactions occur, while the zinc casing acts as the negative terminal because it is the anode where oxidation reactions occur. This is due to their differences in electrode potential and their roles in the electrochemical reaction process.
