Question 19

What do reactive metals do when added to water?

Answer 19

They fizz

Metal + Water -> metal hydroxide + hydrogen

Question 20

What happens when you add a metal to an acid?

Answer 20

Acid + metal -> salt + hydrogen

Question 21

How can you tell how reactive a metal is?

Answer 21

React it with a dilute acid. The more reactive it is, the faster the reaction will happen.
Fill 3 boiling tubes with the same volume of dilute acid (hydrochloric or sulfuric). Add your 3 metals (same size, volume and shape). The speed is determined by the rate of bubbles of hydrogen (can be tested using burning splint test).

Question 22

Do potassium, sodium, lithium and calcium react well with water?

Answer 22

Yes! They react vigorously with water.

Question 23

Does magnesium, zinc and iron react well in water?

Answer 23

They don’t react much at all in water, but do react with steam.

Question 24

What is the general equation for metals reacting with hydrochloric acid?

Answer 24

Metal + hydrochloric acid -> metal chloride + hydrogen

Question 25

What is the general equation for metals reacting with sulfuric acid?

Answer 25

Metal + sulfuric acid -> metal sulfate + hydrogen

Question 26

What is the general equation for metals reacting with nitric acid?

Answer 26

Metal + nitric acid -> metal nitrate + hydrogen

Question 27

What 3 ways can stop iron from rusting?

Answer 27

Barrier methods, galvanising and sacrificial protection.

Question 28

What is the barrier method?

Answer 28

The barrier method prevents iron from rusting, by coating iron with paint/oil/plastic to stop it from coming into contact with water and oxygen. It is a cheap way of protecting iron, however it can scratch off easily, and it is time consuming as you are constantly re-applying the coating.

Question 29

What is galvanising?

Answer 29

Galvanising is a way of preventing iron from rusting by coating it with chunks of zinc. It works because zinc is way more reactive than iron, so the zinc will react with the oxygen and water. It is good because it works when it is scratched, however once it has related it needs re-doing.

Question 30

What is sacrificial protection?

Answer 30

Sacrificial protection is a way of preventing iron from rusting. You put a more reactive metal onto iron, so that the metals reacts with water and oxygen instead of the iron. It is good because it works when scratched, however once it has reacted it needs re-doing. Galvanising is a form of sacrificial protection.

Question 31

What does redox mean?

Answer 31

Redox is the term for reduction and oxidation.

Question 32

What is oxidation?

Answer 32

Oxidation is the gain of oxygen/ the loss of electrons during a chemical reaction.

Question 33

What is reduction?

Answer 33

Reduction is the loss of oxygen/ gain of electrons or gain of hydrogen during a chemical reaction.
