It you know the molar concentration of an acid solution and can measure its pH, the above equivalence allows you to calculate the relative concentration of acid to conjugate base and derive the dissociation constant Ka. To do this, it helps to set up a table that delineates theInitial concen...

What is the dissociation constant of acetic acid? The pH of a 0.10 M HOBr solution is 4.8. What is the value of pKa? Calculate the Ka of an acetic acid solution if the pH is 4.76 and concentration is 176 mM. How can you determine dominant species given pKa?
1) A 50.00mL sample of 0.1000 M hydrochloric acid is exactly neutralised by 23.85 mL of potassium hydroxide solution. How to calculate the molarity of the potassium hydroxide in the solution? What are The pH scale ranges from 0 to 14 a...

Then, by using the molar ratio between KHP and NaOH (1:1), we can calculate the moles of NaOH used. Finally, by dividing the moles of NaOH by the volume of base used, we can calculate the concentration of the base. 3. To determine the moles of HCl needed to neutralize the given ...
How to Calculate the pH of a Buffer The Henderson-Hasselbalch equation solves for the pH of a solution using pKa, which is the negative log of the acid dissociation constant. This value is an equilibrium constant for the reaction of {eq}HA \rightleftharpoons A^- + H^+ {/eq}, which ...
So the acid-base reaction in the quiz above favors water (pKa14) by about 10 orders of magnitude (1010) over acetic acid (pKa4). That means there are roughly 10 billion molecules of water for every molecule of acetic acid. This quiz asks you to calculate the ratio of each acid present...
We next asked how it is possible that long-lived misfolded proteins are able to bypass the post-translational cellular chaperone machinery. To address this question we used coarse-grained Langevin dynamics to calculate the dissociation constant between the chaperone GroEL and three distinct conformational...
