andie 10 Posted February 26, 2007 Hey! I am doing a titration and I need to find out what the pH is. I need to combine sodium acetate and acetic acid together. What are the products of this reaction... is it water and what else???? 0 Share this post Link to post Share on other sites
woelen 18 Posted February 26, 2007 Sodium acetate and acetic acid are conjugate base and acid. The only thing they do is form an equilibrium. The mix of the two forms a buffering solution, with pH depending on concentration of the two chemicals. It makes no sense to titrate sodium acetate with acetic acid, nor the other way around. 0 Share this post Link to post Share on other sites
andie 10 Posted February 26, 2007 actually for this titration i need to know the volumes of the sodium acetate and acetic acid that will make a pH of 5.0 and 4.70. I know that sodium acetate is 1.0 M and acetic acid is 1.0M with a volume of 15.0 mL ... Therefore how would you calculate the volume of sodium acetate needed when you have the volume of acetic acid? 0 Share this post Link to post Share on other sites
Borek 11 Posted February 26, 2007 Start with learning about Henderson-Hasselbalch equation. Then check buffer pH question 1 and buffer pH question 2 - although they don't address specifically your problem, they show how to deal with buffer preparation. Acetic buffer case is not different. 0 Share this post Link to post Share on other sites
