Calculate the pH during the titration of 36 mL of 0.22 M HBr with 0.15 M KOH after 11 mL of the base has been added. Calculate the pH for the following in the titration of 50.0 mL of 0.240 M HCIO (aq) with 0.240 M KOH (aq) after ...
Chemists sometimes use titration to determine the alkalinity of an unknown substance. The term "alkalinity" refers to the degree to which a substance is basic—the opposite of acidic. To titrate, you add a substance with a known [H+] concentration—or pH—to the unknown solution one drop at...

Calculate the pH of a 0.10 mol/L solution of ascorbic acid, H2C6H6O6(aq), and the equilibrium concentrations of H2C6H6O6, HC6H6O6-(aq), and C6H6O6^2-(aq) in this solution. Ascorbic acid is a polyprotic acid. What is a titrant in a titration?
"buffer solution," one which resists changes in pH when you add small amounts of acid. You can represent the extent to which your acid dissociates — and thus changes the solution's pH — using its "pKa" value, and you can calculate this value using data from your titration experiment....
