A) The solution that shows the greater pH at equivalence point is a weak acid solution because the OH- ion concentration is more in that solution. Therefore - In the given acids - HA - is a weak acid HB is a stronger acid B) HA is a weak acid - Hence A- is stronger base than B- Solution A) The solution that shows the greater pH at equivalence point is a weak acid solution because the OH- ion concentration is more in that solution.
