What you add to butylamine to produce a basic buffer solution?

Question:

"Identify a substance that could be added to aqueous butylamine to produce a basic buffer solution (1 mark)"

AQA answers:

"Any strong acid (but not concentrated)
or any amine salt or ammonium salt of a strong acid"

Why couldn't it be water as:

CH3CH2CH2CH2NH2 + H20 => CH3CH2CH2CH2NH3+ + OH-

because when OH- are added there is nothing to remove it.

For a buffer system you need a base and salt of its conjugate acid.

Thanks I forgot to revise basic buffer solutions and realised the answer shortly after I posted. lol :redface:
