The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.

WebHowever it's unnecessary to calculate the pH of strong acid solution using the Henderson-Hasselbalch equation since we can do so using stoichiometry of H+ and assume that strong acids dissociate ~100%. So it's possible to use the Henderson-Hasselbalch equation, but it creates unneeded work when simpler methods are possible. WebWhen you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H 3 O + ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H 3 O +.
