Binary Acid Trend
1. The larger the atom the stronger the acid (weaker bond).
Use when comparing atoms in the same group.
HI > HBr > HCl > HF
2. The more electronegative the atom the stronger the acid.
Use when comparing atoms in the same period.
NH3 < H2O < HF
Oxoacid Trend
1. More oxygens, more acidic (due to resonance)
HClO4 > HClO3
2. More electronegative central atom, more acidic (inductive effect)
HClO4 > HBrO4
Polyprotic Acids
Polyprotic acids are successively less acidic as they donate additional H+.
