Title: How do I use the Henderson Hasselbalch equation to find the pH of the acetic acid - acetate buffer? Post by: nyerramilli on Apr 15, 2013 The only information that I'm given is the molar concentration (in g/mol) of the acetic acid and the acetate
They are both 0.1g/mol HELP!!!! Title: How do I use the Henderson Hasselbalch equation to find the pH of the acetic acid - acetate buffer? Post by: askat on Apr 15, 2013 if they are in equal concentration the pH should equal the pKa which I'm pretty sure is 4.76. the equation i used is pH=pKa+log(A-/HA)
Title: How do I use the Henderson Hasselbalch equation to find the pH of the acetic acid - acetate buffer? Post by: juliaanne82 on Apr 15, 2013 pH=pKa + log ([H+]/[HA])
In your case, [H+] = [HA] therefore ([H+]/[HA]) = 1. Since log 1 = 0, then pH is equal to the pKa of the conjugate acid. |
