Chapter 6: Acids And Bases

Question 1

3 Types of Acids

Answer 1

1. Arrhenius Acid - anything that produces H ions in aqueous solution
   - Arrhenius Base - anything that produces hydroxide ions in aqueous solutions
2. Bronstead and Lowry Acid - anything that donates a proton
   - Bronstead and Lowry Base - anything that accepts a proton
3. Lewis Acid - anything that accepts a pair of electrons
   - Lewis Base - anything that donates a pair of electrons

Question 2

Lewis Acids include molecules with incomplete octet of electrons around the ______ _______,

Answer 2

Central atom

Question 3

Lewis acids include all simple cations except what?

Answer 3

Alki and heavier alkaline earth metal cations

Question 4

Relationship b/n size of cation & charge & strength

Answer 4

Smaller the cation, the stronger the charge, the stronger the acid strength
