The larger the value of the standard reduction potential, the easier it is for the element to be reduced (gain electrons); in other words, they are better oxidizing agents. For example, F 2 has a standard reduction potential of +2.87 V and Li + has −3.05 V: F 2 (g) + 2 e − ⇌ 2 F − = +2.87 V Li + + e − ⇌ Li (s) = −3.05 V
The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at: Temperature 298.15 K (25.00 °C; 77.00 °F); Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species; Unit activity for each solvent and pure solid or liquid species; and
The concentration of zinc in blood plasma stays relatively constant regardless of zinc intake. [207] Cells in the salivary gland, prostate, immune system, and intestine use zinc signaling to communicate with other cells. [217] Zinc may be held in metallothionein reserves within microorganisms or in the intestines or liver of animals. [218]

The oxidation potential for a particular electrode is just the negative of the reduction potential. A standard cell potential can be determined by looking up the standard electrode potentials for both electrodes (sometimes called half cell potentials). The one that is smaller will be the anode and will undergo oxidation.
Zinc is a key mineral that helps our immune system and cell reproduction. Here's what you need to know about the mineral, and where it comes from. This Is What Zinc Does to Your Body
The simplest is when the reference electrode is used as a half-cell to build an electrochemical cell. This allows the potential of the other half cell to be determined. An accurate and practical method to measure an electrode's potential in isolation (absolute electrode potential) has yet to be developed.
While zinc plays an integral role in the body’s overall function and performance, moderation is key. How much zinc do you need? The daily recommended dietary allowance is 8 mg for women and 11 ...
