Q

A base is a substance that accepts hydrogen ions (protons). I.e. It’s a proton acceptor
2
Q
What is Kw?
A
The ionic product of water. It’s temp dependant
Kw = [H^+][OH^-]
3
Q
What relationship allows you to find pH?
A
pH = -log[H^+]
4
Q
What is Ka?
A
The acid dissociation constant.
Ka = ([H^+][A^-] )➗[HA]
5
Q
What does pKa = ?
A
-log(Ka)
6
Q
