- Summarize the relationship between pKa and base strength by completing the followingsentences: a. For a given base, the higher the pKa of its conjugate acid, the stronger or weaker the base. b. For a given base, the lower the pKa of its conjugate acid, the stronger or weaker the base.Predict the position of equilibrium for this acid-base reaction.Identifying the major species in weak acid or weak base... The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row.
