The formula for calculating the pH of a weak acid solution is derived from the equilibrium constant expression for the dissociation of the weak acid. Let's take the example of acetic acid (CH3COOH) to illustrate the calculation. First, we need to write the dissociation reaction of acetic acid...
To calculate the pH of a weak acid, it is important to note that pH has no units, thus it is required to define it with H+ ion concentration.

Let, a monoprotic weak acid be HA which ionizes in its aqueous solution and produces an equal molar concentration of H3O+ and A− ions. Its acid dissociation constant be ka. Now, ka of HA is defined as ka=[H3O+]×[A−][HA] ---> Equation...
How do you calculate the pH of a buffer solution? To calculate the pH of a buffer solution, the Henderson-Hasselbalch equation is used, pH = pka + log(acid/base). If working with a weak acid and conjugate base, the pka is found and plugged into the concentrations for each added to ...
