***CHEMISTRY MEDAL IN EXCHANGE FOR HELP***
What would the hydroxide ion concentration be if the hydrogen ion concentration was 1 x 10-5 M?

I don't know how to calculate the hydroxide ion concentration with the hydrogen ion concentration. Can someone please provide a mathematical explanation?

We have a half page of these kinds of problems and I sincerely want to know how to solve them. Thanks in advance!

Answer 1

I'm going to put a few things here since I helped you previously with a similar question.

- To calculate pH you need the hydronium ion and you use pH = - log [H3O^+]

-To calculate the Hydronium Ion Concentration from pH we need to use [H3O^+] = 10^-pH or in words [H3O^+] is equal to 10 to the power of a negative pH

-To calculate pOH we are going to use pOH = -log [OH^-]

- To calculate the Hydroxide Ion Concentration from pOH we are going to use the formula [OH] = 10^-pOH or in words [OH] is equal to 10 to the power of a negative pOH.
