1

When does ionization occur and what does it produce from an acid?

Occurs when an ionic compound dissociates in water.

Produces a proton (H+) or a hydronic ion (H3O+)

2

What is Ka, if Ka is high Whats favoured?

Acid ionization constant -reflects fraction of an acid that is ionized.

Products are favoured or the acid is strong. (Dissociates almost completely)

3

Describe Arrhenius Acids and Bases

Acids- substance that yields a proton (H+)

Bases- substances that yield a hydroxide ion (OH-)

4

Describe Brønsted- Lowry acids and bases

Acid- Proton donor

Base- Proton acceptor

Can now include bases that don’t have hydroxide ion (NH3)

5

Describe Lewis Acids and Bases

Acids- accept a pair of electrons

Bases- donate a pair of electrons

6

Kw

Ion product constant for water and aqueous solutions

1.0x10-14
[OH-][H+]

7

What does ionizing partially result in

Equilibrium

8

Why do some acids have more than 1 Ka?

They have more than 1 ionizable hydrogen

Ka decreases with each ionizable proton because they don’t want to get more negative by losing more protons

9

Why is water not in Ka Formula

Water is a liquid and doesn’t change in concentration

10

Base dissociation constant

kB=[conjugate acid][OH-]
—————————-
[base]

11

What does concentrated and dilute indicate

How much of an acid or base is dissolved in solution

12

Hydroxide?

A water molecule that looses a hydrogen ion and becomes a negatively charged hydroxide ion (OH-)

13

Hydronium?

Water molecule that gains a hydrogen ion and becomes a positively charged hydronium ion (H3O+)

14

pH?

pOH?

Negative logarithm of the hydrogen ion concentration

Negative logarithm of the hydroxide ion concentration

15

Amphoteric

Acts as both an acid and a base (water)

16

Monoprotic
Diprotic
Triprotic

Having 1 ionizable hydrogen

17

Conjugate acid

Conjugate base

Particle formed when a base gains a hydrogen ion

Particle that remains when an acid has donated a hydrogen ion

18

Strong base?

Weak base?

Completely dislocated into metal ions and hydroxide ions in aqueous solution

Reacts with water to from hydroxide ion and the conjugate acid of the base.
