Webbis the value of the standard emf of a cell in which molecular hydrogen is oxidized to solvated protons at the left-hand electrode. For example, the standard potential of the Zn2+ Zn electrode, denoted E°(Zn2+ Zn), is the emf of the cell in which the reaction Zn2+(aq) + H 2 → 2H +(aq) + Zn takes place under standard conditions.

In chemistry, the standard state of a material (pure substance, mixture or solution) is a reference point used to calculate its properties under different conditions. A superscript circle ° (degree symbol) or a Plimsoll (⦵) character is used to designate a thermodynamic quantity in the standard state, such as change in … Visa mer Many standard states are non-physical states, often referred to as "hypothetical states". Nevertheless, their thermodynamic properties are well-defined, usually by an extrapolation from some limiting condition, such as … Visa mer At the time of development in the nineteenth century, the superscript Plimsoll symbol ( ) was adopted to indicate the non-zero nature of the … Visa mer • Standard conditions for temperature and pressure • Standard molar entropy Visa mer WebbChemical symbols are the abbreviations used in chemistry for chemical elements, ...
