Types of Acid/Base Reactions 1. Strong Acid + Strong Base ----> Water + salt ... pH = Neutral Example: HCl + NaOH ----> H 2 O + NaCl Net Ionic Equation: H 3 O + + OH - ----> 2H 2 O 2. Weak Acid + Strong Base ----> Water + weak base ... pH = Basic Example: HF + NaOH ----> H 2 O + NaF Net Ionic Equation: HF + OH - ----> H 2 O + F - Conjugate base of a weak acid = Basic. 3. Strong Acid + Weak Base ----> Weak Acid ... pH = Acidic Example: HCl + F - ----> HF Net Ionic Equation: H 3 O + + F - ----> HF + H 2 O Conjugate acid of a weak base = Acidic. 4. Weak Acid + Weak Base ---- > Weak Acid + Weak Base ... pH depends upon relative K a values Example and NIE: HCN + F - ---- > HF + CN - Strong bases react completely with ANY acid.
