Calculating the ph of a weak acid solution
WebCalculate the pH at these volumes of added base solution: (a) 0.00 mL (b) 12.50 mL (c) 25.00 mL (d) 37.50 mL Solution (a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then WebSep 21, 2024 · The pH will change as a result of many factors. Adjustment can be accomplished with different chemicals, depending on the tested pH. High pH can be lowered with liquid \(\ce{HCl}\) (unsafe material) or sodium bisulfate. The bisulfate anion is a weak acid and can dissociate partially in solution. To increase pH, use sodium carbonate.
