1

What is an acid?

An acid is a proton donor

2

What is a base?

A base is a proton acceptor

3

In the reaction HA + B ⇌ BH^+ + A^-, what are the conjugate acid base pairs and why?

HA and A^- are connected by the loss and gain of a proton and so are an acid-base conjugate pair
B and BH^+ are connected by the loss and gain of a proton and are an acid-base conjugate pair

4

In the reaction HA + B ⇌ BH^+ + A^-, which acts as the acid and base in the forward reaction?

HA is the acid and B is the base

5

In the reaction HA + B ⇌ BH^+ + A^-, which acts as the acid and base in the reverse reaction?

BH^+ is the acid and A^- is the base

6

What type of acid is sulfuric acid and what is its conjugate base?

Strong
Hydrogensulfate ion (HSO4^-)

7

What type of acid is hydroiodic acid and what is its conjugate base?

Strong
Iodide ion (I^-)

8

What type of acid is hydrobromic acid and what is its conjugate base?

Strong
Bromide ion (Br^-)

9

What type of acid is hydrochloric acid and what is its conjugate base?

Strong
Chloride ion (Cl^-)

10

What type of acid is nitric acid and what is its conjugate base?

Strong
Nitrate ion (NO3^-)

11

What type of acid is the hydroxonium ion and what is its conjugate base?

Strong
Water (H2O)

12

What type of acid is the hydrogen sulfate ion and what is its conjugate base?

Weak
Sulfate ion (SO4^2-)

13

What type of acid is hydrofluoric acid and what is its conjugate base?

Weak
Fluoride ions (F^-)

14

What type of acid is ethanoic acid and what is its conjugate base?

Weak
Ethanoate ion (CH3COO^-)

15

What type of acid is carbonic acid and what is its conjugate base?

Weak
Hydrogencarbonate ion (HCO3^-)

16

What type of acid is the ammonium ion and what is its conjugate base?

Weak
Ammonia (NH3)

17

What type of acid is the hydrogencarbonate ion and what is its conjugate base?

Weak
Carbonate ion (CO3^2-)

18

What type of acid is water and what is its conjugate base?

Weak
Hydroxide ion (OH^-)

19

What is a strong acid?

A strong acid is one that is totally ionised in aqueous solution, forming hydrated hydrogen ions, H3O^+ (hydroxonium) e.g. HCl

20

What is a weak acid?

A weak acid is one that is only very slightly ionised in aqueous solution e.g. ethanoic acid

21

What is a strong base?

A strong base is totally ionised in aqueous solution, forming hydroxide ions, OH^- e.g. NaOH

22

What is a weak base?

A weak base is protonated to only a small degree in solution so only forms a small proportion of hydroxide ions
