1
Q

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

A

Occurs when an ionic compound dissociates in water.

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

2
Q

What is Ka, if Ka is high Whats favoured?

A

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

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

3
Q

Describe Arrhenius Acids and Bases

A

Acids- substance that yields a proton (H+)

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

4
Q

Describe Brønsted- Lowry acids and bases

A

Acid- Proton donor

Base- Proton acceptor

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

5
Q

Describe Lewis Acids and Bases

A

Acids- accept a pair of electrons

Bases- donate a pair of electrons

6
Q

Kw

A

Ion product constant for water and aqueous solutions

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

7
Q

What does ionizing partially result in

A

Equilibrium

8
Q

Why do some acids have more than 1 Ka?

A

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
Q

Why is water not in Ka Formula

A

Water is a liquid and doesn’t change in concentration

10
Q

Base dissociation constant

A

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

11
Q

What does concentrated and dilute indicate

A

How much of an acid or base is dissolved in solution

12
Q

Hydroxide?

A

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

13
Q

Hydronium?

A

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

14
Q

pH?

pOH?

A

Negative logarithm of the hydrogen ion concentration

Negative logarithm of the hydroxide ion concentration

15
Q

Amphoteric

A

Acts as both an acid and a base (water)

16
Q

Monoprotic
Diprotic
Triprotic

A

Having 1 ionizable hydrogen

2

3

17
Q

Conjugate acid

Conjugate base

A

Particle formed when a base gains a hydrogen ion

Particle that remains when an acid has donated a hydrogen ion

18
Q

Strong base?

Weak base?

A

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.
