To calculate the pH of an acid buffer, the Henderson-Hasselbalch equation is used, which is pH = pKa + log(acid/base). The acid's concentration is on top of the fraction, and the conjugate base's is on the bottom. What is the pH of a buffer? The pH of a solution, buffer or ...

The strengths of acid and bases can be assigned a value:pKa, or theacid dissociation constant, the pH value at which half of an acid has donated its protons while the other half remains in the conjugated state. (Bases have, you guessed it, pKbvalues.) Stronger acids thus have lower pKa...

Re: how do you calculate the net charge of a peptide? « Reply #4 on: September 06, 2010, 04:30:35 PM » Charges on proteins result from simple acid/base chemistry. Acidic and basic groups on the proteins lose/gain protons depending on the pH of the solution. The loss or gain...
Calculate the pH of a buffer solution that is 0.40 M in both HC2H3O2 and NaC2H3O2. Between benzoic acid and acetic acid, which is a stronger acid without looking to pKa value? Why A buffer is prepared by mixing 44.2 mL of 0.209 M NaOH with 141.2 mL of 0.231 M acetic acid. What ...
Decide on the pH for your buffer. This pH should be within one pH unit from the pKa of the acid/conjugate base. So, you can prepare a buffer at pH 2 or pH 7, for example, but pH 9 would be pushing it. Use theHenderson-Hasselbachequation to calculate how much acid and base you ...
