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 i’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.
