pH scale
2
Water In pure water the [H+] and [OH-] must be the same because 1 ion of each is formed when it breaks apart Kw = water equilibrium constant Kw = 1 x = [H+] x [OH-]
3
Kw problems IF the [OH-] = 0.01 M what is the [H+]?
If the [H+] = M what is the [OH-]?
![Kw problems IF the [OH-] = 0.01 M what is the [H+]](http://slideplayer.com./slide/11684911/65/images/3/Kw+problems+IF+the+%5BOH-%5D+%3D+0.01+M+what+is+the+%5BH%2B%5D.jpg "If the [H+] = M what is the [OH-]")
4
pH pH = pouvoir hydrogene (French) = power of H pH scale is from 0-14
Acids: 0-6.9 Neutral 7 Base pH = -log of [H+]
5
pH problems What is the pH of a solution with a [H+] = .000001 M?
Is this an acid or base?

What if you know the pH? [H+] = 10-pH If the pH is 4 what is the [H+]?
What is the [OH-]?

7
pH vs pOH pH + pOH = 14 What is the pH if the pOH is 11?
What is the pOH if the pH is 6?
8
Challenge problem If the [H+] is 0.000000001M what is the
[OH-]? pH? pOH? Is this an acid or base?
