Weak acids with relatively higherKavalues are stronger than acids with relatively lowerKavalues. When a solute is added to a solvent, the vapor pressure of the solvent (above the resulting solution) is less than the vapor pressure above the pure solvent. Screen capture done with Camtasia Studio 4.0. Because the concentration of water is extremely large and virtually constant, the water is not included in the expression. Here are some of the values of weak and strong acids and bases dissociation constants used by BATE when calculating pH of the solution and concetrations of all ions present. Ka the acid dissociation constant and Kb the base dissociation constant are measures of the extend of dissociation of a weak acid or base in equilibrium.
