Draw the pH scale using a number line. Include number labels and the terms "acid" "base" & "neutral"
number line 0-14
If you are given [H+] value and want to know the pH, which formula would you use?
pH = -log[H+]
Bronsted-Lowry acids _______ H+ while bases _______ H+
(gain? or accept?)
donate (lose) ; accept (gain)
