Answer 3

H2SO4

Question 4

Strong Acid

Answer 4

HNO3

Question 5

Strong Acid

Answer 5

HClO4

Question 6

Strong Acid

Answer 6

HClO3

Question 7

Strong Acid

Answer 7

Hl

Question 8

Ka Definition

Answer 8

How easily can a proton come off a HA

Question 9

Low Ka & High pHa =
(Does it favor reactants or products)

Answer 9

Weaker acid that is favors reactants (hard to make products) & is harder to get proton off HA

Question 10

High Ka & Low pHa =
(Does or favor reactants or products)

Answer 10

Stronger acid that is favors products (easy to make products) & is easy to get proton off HA

Question 11

Acid (Arrhenius Definition)

Answer 11

Produce H+(aq) as a product

Question 12

Acid (Br∅nsted-Lowy Definition)

Answer 12

H+ Donor

Question 13

Base (Arrhenius Definition)

Answer 13

Produce OH-(aq)

Question 14

Base (Brønsted-Lowry Definition)

Answer 14

H+ Acceptor

Question 15

What action can destroy a buffer?

Answer 15

When adding a base/acid can eliminate a base/acid concentration

Question 16

A buffer is most effective (most resistant to pH changes) when

Answer 16

• The concentrations of acid and conjugate base are high
• The concentrations of acid and conjugate base are equal

Question 17

Greatest Buffer Capacity has

Answer 17

• Acid & Conjugate Base
• High concentration (doesn’t have to be equal)

Question 18

The greater the Ka value

Answer 18

The stronger the acid & the weaker its conjugate base

Question 19

pH = 7 at the equivalence point when

Answer 19

There is a strong acid and strong base titration

Question 20

pka = pH at the half equivalence point when

Answer 20

There is a
Strong Base/Weak Acid Titration
Strong Acid/Weak Base Titration
