The standard reduction potential is measured under standard conditions: T = 298.15 K (25 °C, or 77 °F), a unity activity (a = 1) for each ion participating into the reaction, a partial pressure of 1 atm (1.013 bar) for each gas taking part into the reaction, and metals in their pure state. The standard reduction potential is defined relative to the standard hydrogen electrode (SHE) used as reference electrode, which is arbitrarily given a potential of 0.00 V. However, because these can also be r… WebMn+2, Mn+3 and Mn+4 species, redox potential, pH, and dissolved species ofbicarbonate and sulfate. The solubility ofmanganese is shown by graphs as a function of Eh and pH in the absence ofsulfate and in the presence ofseveral different fixed activities of bicarbonate and sulfate rangingfrom 10 to 2,000 ppm (parts per million).
