TOPIC 12: ACID-BASE EQUILIBRIA

Question 1

What is a Bronsted-Lowry Acid?

Answer 1

A proton donor

Question 2

What is a Bronsted-Lowry Base?

Answer 2

A proton acceptor

Question 3

Definition of a strong acid and give an example

Answer 3

1. Dissociate completely in water nearly all H+ ions are released.
2. Example is HCL

Question 4

Definition of a Weak Acid and give an example

Answer 4

1. Dissociate only partially in water-some H+ ions are released
2. Example is Ethanoic acid

Question 5

What is a conjugated acid-base pair?

Answer 5

A pair that contains two species that can be interconverted by proton transfer

Question 6

How does an acid produce H+ ions in solution

Answer 6

The acid reacts with water and donated a proton to form H3O+. A dative covalent bond is formed between one of the oxygens lone pairs in the water molecule and a hydrogen from the acid

Question 7

Define a Monoprotic acid

Answer 7

Substance that donates one proton

Question 8

Define a Monoprotic base/Monobasic

Answer 8

Substance that only accepts one proton

Question 9

Define Diprotic acid

Answer 9

Substance that can donate two protons

Question 10

Define Diprotic base

Answer 10

Substance that can accept two protons

Question 11

Define Amphoteric. Give an example

Answer 11

Substance that can behave as an acid or a base

Example is Water
