Dissociation constants and standard enthalpy for weak acids/bases
Description
Equilibrium constants (k) and corresponding standard enthalpy of reaction values (deltah) for significant acids in water influencing pH at equilibrium. Includes carbonate, sulfate, phosphate, and hypochlorite. Standard enthalpy of reaction is calculated by taking the sum of the enthalpy of formation of each individual component minus the enthalpy of formation of the final product. e.g., the standard enthalpy of reaction for water can be calculated as: deltah_h2o = deltah_f_oh + deltah_f_h - deltah_f_h2o = -230 + 0 - (-285.83) = 55.83 kJ/mol. See MWH (2012) example 5-5 and Benjamin (2002) eq. 2.96.
