Get … WebJun 5, 2024 · If we wish to find the hydronium ion concentration ([H 3 O +]) and the pH of a solution, we need to know both the strength of the acid (or base) and the concentration of the acid (or base). We will find that we need to treat strong acids (and bases) differently than weak acids (and bases) based on the extent to which they react with water.

Web[H3O+] = 10¯pH [H3O+] = 10¯5.75 [H3O+] = 1.78 x 10¯6M (c) [OH¯] = 10¯pOH [OH¯] = 10¯8.25 [OH¯] = 5.62 x 10¯9M You could also have done this: (1.78 x 10¯6) ([OH¯]) = 1.00 x 10¯14 (d) pH 7, therefore acidic. Example #4:pOH = 3.20. (a) pH (b) [H3O+] (c) [OH¯] (d) acid, base, neutral? Solution: (a) pH + pOH = 14.00 pH = 14.00 − 3.20 = 10.80 The hydrated proton is very acidic: at 25 °C, its pKa is approximately 0. The values commonly given for pKa (H3O ) are 0 or –1.74. The former uses the convention that the activity of the solvent in a dilute solution (in this case, water) is 1, while the latter uses the value of the concentration of water in the pure liquid of 55.5 M. Silverstein has shown that the latter value is thermodynamically unsupportable. The disagreement comes from the ambiguity that to define pKa of H3O in water, … port forwarding on virtualbox

WebSep 9, 2024 · The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34? On a calculator, calculate 10-8.34, or “inverse” log ( – 8.34).
