    This gives the SCE a potential of +0.248 V vs. SHE at 20 °C and +0.244 V vs. SHE at 25 °C, [1] but slightly higher when the chloride solution is less than saturated. For example, a 3.5M KCl electrolyte solution has an increased reference potential of +0.250 V vs. SHE at 25°C while a 1 M solution has a +0.283 V potential at the same temperature.

    Minor chords are noted with a dash after the number or a lowercase m; in the key of D, 1 is D major, and 4- or 4m would be G minor. Often in the NNS, songs in minor keys will be written in the 6- of the relative major key. So if the song was in G minor, the key would be listed as B ♭ major, and G minor chords would appear as 6-.

    The types of physical measurements required under the Rockwood definition are similar to those required under the Trasatti definition, but they are used in a different way, e.g. in Rockwood's approach they are used to calculate the equilibrium vapour pressure of the electron gas. The numerical value for the absolute potential of the standard ...
