pH Notes
What is pH?
pH is the measure ofthe amount of free H(H+) in a solution.
pH Scale
Measured 1-14
1 = Highly acidic14 = Highly basic
pH ExtremesAcid- an acidic solutionhas a high amount of free H+
Base- a basic solutionhas more OH- than H+
Water
Water has a pH of 7
NEUTRAL
Means it has equalparts H+ and OH-
pH Implications- Can help break molecules
down- Can change the shape
of molecules- Can be used to
control body processes
BuffersWeak acids and bases are used inyour body as chemicalsthat minimize drasticchanges in body pH
Why?
Acids + Bases =???NaOH + HCl _______ + ________
