Lesson 1: Acids & Bases
Arrhenius acid and base
Arrhenius acid is a substance that produces H+ (H3O+) in water
Arrhenius base is a substance that produces OH- in water
Brønsted – Lowry
Acids – proton donor
Bases – proton acceptor
Lewis acid and base
Lewis acid - a substance that accepts an electron pair
Lewis base - a substance that donates an electron pair
Types of Acids and Bases
The strength of an acid (or base) is determined by the amount of IONIZATION.
HNO3, HCl, HBr, HI, H2SO4 and HClO4 are the strong acids.
Weak acids are much less than 100% ionized in water.CH3CO2H
Strong Base: 100% dissociated in water.
Weak base: less than 100% ionized in water such as ammonia
Amphoteric
These are compounds that can act as both acids and bases depending on what it is reacting with.

HCO3-
HC2O4-
H2PO4-
