WebVideo transcript. - [Voiceover] pH is defined as the negative log base 10 of the concentration of hydronium ions. Let's say we want to find the pH of water. To find the pH of water, we would take the negative log of the concentration of hydronium ions. For water, at 25 degrees Celsius, the concentration is 1.0 times 10 to the negative seven molar. 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

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. churchill high school football game wpg
