Arrhenius acid
a compound that produces H3O+ ions in aqueous solutions
Arrhenius base
a compound that produces OH– ions in aqueous solutions
Do strong acids have a large Ka or small Ka?
Very large Ka
Do weak acids have a large Ka or small Ka?
Small Ka
What are the types of strong acids?
o Hydrohalic acid, HCl, HBr and HI
o Oxoacids in which the number of O atoms exceeds the number of ionizable
protons by two or more, such as HNO3, H2SO4 and HClO4
What are the types of weak acids?
o Hydrohalic acid: HF
o Acids in which H is not bonded to O or to a halogen: HCN, H2S
o Oxoacids in which the number of O atoms equals or exceeds by one the
number of ionizable protons: HClO, HNO2, H3PO4
o Organic carboxylic acids RCOOH
What are types of strong bases?
hydroxides of groups I and II metal ions
What are some types of weak bases?
Amines
In water, what is [OH-] and [H+]?
Kw = [H3O+][OH-] = 1.0 × 10-14
[H3O+]=[OH-] = 1.0 × 10-7 M

Acid-Base Properties of Salts
Henderson–Hasselbalch Equation
To be used in a buffer system:
Weak Acid + Conjugate Base
What is a buffer?
solution that resists changes in pH when small quantities of acids or bases are added to it
