Flashcards in Acids, Bases And Neutralisation Deck (24):
1

What do all acids contain in their formulae?

Hydrogen ions.

2

What happens when an acid is dissolved in water?

Hydrogen ions are released in solution.

3

What does a strong acid do in water?

It releases all of its hydrogen ions which is known as complete dissociation.

4

What is a good example of a strong acid?

HCl

5

What does a weak acid do when dissolved in water?

It only releases a small proportion of hydrogen ions into the solution (partial dissociation).

6

What type of acid tends to be weak?

Organic acid.

7

Give an example of a weak acid.

Ethanoic acid.

8

What are the different types of base?

Metal oxides
Metal hydroxides
Metal carbonates
Ammonia

9

What is the molecular formula of ammonia?

NH3

10

What does a base do to an acid?

It neutralises an acid to form a salt.

11

What is an alkali?

This is a base that dissolves in water releasing hydroxide ions into a solution.

12

What are the three metal oxide bases?

MgO
CaO
CuO

13

What are the common metal carbonate bases?

Na2CO3
CaCO3
CuCO3

14

What are the three common alkali bases?

NaOH
KOH
NH3

15

What part of the acid reacts with the base in neutralisation?

The hydrogen ions.

16

What are the hydrogen ions replaced by in neutralisation?

Metal or ammonium ions.

17

What salt is produced when hydrochloride acid reacts with sodium carbonate?

Sodium chloride

18

What salt is produced from the reaction of sulphuric acid and sodium carbonate?

Sodium sulfate

19

What is the formula of sodium chloride?

NaCl

20

What is the formula of sodium sulfate?

Na2SO4

21

What is formed from the neutralisation of an acid with a metal oxide or hydroxide?

A salt and water only.

22

What happens when an alkali and acid reacts?

A salt and water only.

23

When an alkali and acid reacts, what are the reactant states?

The reactants are in solution (aqueous)

24

What is produced in the neutralisation of acids with metal carbonates?

A salt, water and carbon dioxide gas.
