... Correct Response: D. The combination of chemicals is that of a weak acid and a strong base. This conclusion can be drawn because the equivalence point on the graph corresponds to a pH greater than 7. It is clear that a weak acid is being titrated with a strong base (instead of a strong base being ti ...
