Mm I chose A for that one cause I was thinking that sodium hydroxide totally neutralizes the ethanoic acid, so overall you get a strong base solution, which is not a buffer.

Hello, why can't Sodium Hydroxide and Ethanoic acod be mixed to create a buffer solution? I would have thought that adding sodium Hydroxide and sodium ethanoate would be purely basic, and so could not be a buffer? This is question 6, multiple choice.

Having not done the question, Sodium Hydroxide is a strong base so you cannot use that for a buffer solution... Has to be weak acid and base...

=/ one of the other choices is NaOH and CH3COONa, and apparently that acts as a buffer

I dunno how that works...
If you add base to that solution though I don't know where the H+ ions come from to neutralise it - and I thought that buffer solutions are meant to be able to neutralise or partly neutralise a solution of acid or base...
