◉ How do you classify a salt as acidic or basic
Answer: strongest one wins
◉ What is the classification of the salt....
if they are both strong?
if they are both weak?
Answer: if both strong: neutral
if both weak: Ka>Kb=acidic
Ka<Kb=basic
◉ How to solve for Ka
Answer: Products/reactants
[H3O+][A-]/[HA]
◉ Stronger acid =
Stronger base =
, Answer: acid = ↑Ka, ↓pKa, ↓pH, ↑pOH, ↑[H+], ↓[OH-]
base = ↑Kb, ↓pKb, ↑pH, ↓pOH, ↓[H+], ↑[OH-]
◉ as concentration increases......% dissociation _________
Answer: concentration ↑, % dissociation ↓, ↑buffer capacity
◉ equation for pKa
Answer: pKa = -log(Ka)
◉ Kw equation
Answer: Ka x Kb = Kw
