WebAt the standard state temperature of 298.15 K (25.00 °C; 77.00 °F), it is approximately 25.69 mV. The thermal voltage is also important in plasmas and electrolyte solutions (e.g. the Nernst equation ); in both cases it provides a measure of how much the spatial distribution of electrons or ions is affected by a boundary held at a fixed voltage. WebKb is the base dissociation constant, while pKb is the – log of the constant. Kb = [B +][OH –]/[BOH] pKb = – log Kb. A significant Kb value implies a strong base’s high amount of dissociation. A stronger base is indicated by a lower pKb value. pKa and pKb are related by the simple relation: pKa + pKb = 14.
