  • i might say that there could be a typo or some kind of mistake using fact of actuality, from what i understand, in certainty the launch of the acetate ion from the inclusion of sodium acetate might want a buffer answer. for that reason, i might say that (a) ought to be the appropriate answer. in spite of the reality that, NaOH ought to, for yet another excuse that iā€™m now no longer wakeful of, want a buffer answer. yet I honestly have by skill of no skill heard of one in each and every of those solid judgment and that i doubt no remember if something so particular ought to be examined of you.

  • The answer is A. I always used that buffer in my lab. It is called Acetate buffer
