Joanna is performing a reaction that generates a moderate amount of hydroxide. To mimic biological conditions (most bodily fluids in living organisms retain a relatively constant pH around 7), she knows that she needs to add a buffer to the reaction. Which of the following will MOST effectively neutralize the OH− ions produced by the reaction

As for your question, I know to forget to put the options, specifically that your question is incomplete.

Explanation:

Although it could help you by telling you that always a reaction that seeks to balance the pH, and achieve neutrality ... It is necessary to achieve a concentration of OH equal to that of H +, in this way the hydroxyl and the protons.
