Rearranging that equation after taking the opposite of the base-10 logarithm of both sides produces this formula.
This equation is most often used to approximate a value found experimentally using a glass-electrode voltmeter that measures activity. The inspiration behind this equation came in 1908 when its first namesake wrote an equation for the behavior in aqueous solution of carbon dioxide. When carbon dioxide dissolves in water, it produces a compound H2CO3 which is of the class of compounds described by this equation. Rearranging that equation after taking the opposite of the base-10 logarithm of both sides produces this formula. Models for the class of compounds described by this equation include ones by Arrhenius, Lewis, and Brønsted and Lowry. FTP, name this doubly- eponymous logarithmic equation that adds the pKa to the relative concentrations of conjugate base and acid of a buffer solution to yield the pH.
