Buffer intensity is the resistance of a solution to a pH change when a strong acid or base is added. Which of the following solutions has the greatest buffer intensity? А. a solution containing 1.0 M NH3/1.0 M NH4+ В. a solution containing 0.10 M NaOH/0.10 M HCI С. a solution containing 1.0 M NaOH/1.0 M HCI D. a solution containing 0.10 M NH3/0.10 M NH4+
