Achieve Week 10 #5

[Bailey Wallace 3A]

Determine the [H+], [OH−], and pOH of a solution with a pH of 3.51 at 25 °C.

I was able to calculate the pOH but I am having a hard time with the [H+] and [OH−], can anyone help me?

[Ashley M 2E]

To find [H+] and [OH-], use the equation pH=-log[H+] and pOH=-log[OH-]. To undo the log, you basically take 10^-pH and 10^-pOH to find your answer.

I am also having trouble with this problem. I was able to find the pH, but how to I find the [OH-] value to plug into the log equation?

[Tyler_Kim_2G]

Hey Holland, if you know the [H+] value, you could determine the [OH-] value by the relationship [OH-]=(1.0 x 10^-14)/[H+]. If you do not already know the [H+], you can use the pH value and undo the log by using the relationship stated above.
