Use the value for the moles of H + to calculate … WebpKw = pH + pOH = 14. Equation 1.17.11 is correct only at room temperature since changing the temperature will change Kw. The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4.

http://www.biology.arizona.edu/biomath/tutorials/applications/pHQ3t.html 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 +.
