New here, hello :)
Which of following mixtures will be a buffer when dissolved in a liter of water?
a. .1 mole of Ba(OH)2 and .2 mole of HBr
b. .3 mole of KCl and .3 mole of HCl
c. .4 mole of NH3 and .4 mole of HCl
d. .2 mole of CH3COOH and .1 mole of NaOH
e. .2 mole of HBr and .1 mole of NaOH
My guess is that it has something to do with being a weak acid/base. Unfortunately, this doesn't make sense, because the answer is D, and D has acetic acid and NaOH, which aren't weak?
Thanks in advance :)
