To calculate the pH of a weak acid, it is first important to keep in mind that pH has no units, thus it is required to define it with H+ ion concentration. pH is a quantitative measure of acidity or basicity of aqueous or other liquids. The formula to calculate pH of weak acid is...

Acetic acid, commonly known as ethanoic acid, is a weak acid having the formulaCH3COOHin its chemical formula. It’s the active ingredient of vinegar, which is an acetic acid solution in water with a concentration of 4–7%. When dissolved in water, acetic acid only partially dissociates into...
pH, Ka, andpKaare all related to each other. For an acid HA: Ka= [H+][A-] / [HA] pKa= - log Ka pH = - log([H+]) At the halfway point on an equivalence curve, pH = pKa. Ka of Weak Acids Ka of Weak Acids NameFormulaKapKa ...
Weak Acid pH Calculator This is a calculator to find values of a weak acid dissociation reaction. All concentrations are measured in M (mol/liter). Values are found using the equilibrium constant formula, where the product of the concentration of products to the power of their coefficients is ...

Because we know that a pH of 7 is neutral, we can figure that a substance with a low pH is a very strong acid. An acid with a pH approaching 7 is a weak acid. A substance with a pH of 7 is neutral, as we have learned. As the pH of a substance rises from 7, it turns fro...
