To create a more manageable number, chemists define the pKa value as the negative logarithm of the Ka value: pKa = -log Ka. Using Ka and pKa To Predict Equilibrium and Strength of Acids K a may be used to measure the position of equilibrium: If K a is large, the formation of the products of the dissociation is favored. Plug all concentrations into the equation for K a and solve. - Will you have more vegetables?
