Calculate the ph of a solution
WebMar 23, 2024 · The pH is thus –log (0.100) = 1.000. The formula for pH is pH = -log [H+]. This means pH is the negative base 10 logarithm (“log” on a calculator) of the hydrogen ion concentration of a solution. To calculate it, take the log of the hydrogen ion concentration and reverse the sign to get the answer. 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
