Calculate the concentration (in M) of hydronium ions in a solutino at 25 C with a pOH of 4.223 [Solved]

You may prefer to determine the pH from pH pOH = 14.000
pH = 14.000 4.223 = 9.777
[H ] = 10^-pH = 10^-9.777 = 1.6710^-10

There are several ways to get the answer.
Since you are given the pOH, you can calculate the [OH-] by 10^-pOH (10^-4.223 = 5.98410^-5)
Then you know that at 25 deg C, [OH-][H ] = 1.0010^-14 = Kw
[H ] = 1.0010^-14 / 5.98410^-5 = 1.6710^-10

You may prefer to determine the pH from pH pOH = 14.000
pH = 14.000 4.223 = 9.777
[H ] = 10^-pH = 10^-9.777 = 1.6710^-10

You may prefer to determine the pH from pH pOH = 14.000
pH = 14.000 4.223 = 9.777
[H ] = 10^-pH = 10^-9.777 = 1.6710^-10
