H I think that is what you call it. The acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution while the base dissociation constant (Kb) is a measure of basicitythe base's general strength. Note the interface between liquid water (below) and water vapor (above). So you can only have three significant figures for any given phosphate species. The boiling point of the solvent above a solution will be greater than the boiling point of the pure solvent whether the solution contains a non-volatile solute or a volatile solute. Kb is the molal boiling point elevation constant, and E) 8. there are fewer water molecules in the vapor (i.e., lower vapor pressure) above the NaCl solution than in the vapor above pure water, and. {{ nextFTS.remaining.days }} Thus the product of the acid constant for a weak acid and the base constant for the conjugate base must be Kw, and the sum of p Ka and p Kb for a conjugate acid-base pair is 14. The logarithmic constant (pKa) is equal to -log10(Ka). K_b for the reaction of HCO_2^- ion with water is 5.6 times 10^{-11}. * Compiled from Appendix 5 Chem 1A, B, C Lab Manual and Zumdahl 6th Ed.
