Why is this a buffer system?
« on: August 12, 2006, 02:07:21 PM »
Can someone kindly explain to me why the following is a buffer system?

5 ml of 1.00M HCl and 10 ml of 1.00M Sodium Acetate

I know it says that a buffer is a combo of a weak acid and its conj. base (vice-versa), but isn't HCl a strong acid ??? I'm so confused...

What will HCl do to acetate? Remember that acetic ion is a base.

Ohhh... HCl reacts with the sodium acetate to produce acetic acid which is a weak acid... duhh.... lol, Thanks again Borek!
