Reactivity of Metals

Question 1

How can you determine a metals reactivity with water or an acid?

Answer 1

How vigorous the reaction is

Question 2

How can a metal be arranged in a reactivity series based of a displacement reaction?

Answer 2

If a metal displaces another metal from its compound it it more reactive

Question 3

Order the reactivity series?

Answer 3

Potassium
Sodium
Lithium
Calcium
Magnesium
Aluminium
Zinc
Iron
Copper
Silver
Gold

Question 4

What is reduction?

Answer 4

Gain of electrons, loss of oxygen

Question 5

What is oxidisation?

Answer 5

Loss of electrons, gain of oxygen

Question 6

What is redox?

Answer 6

When oxidation and reduction happen at the same time

Question 7

What is an oxidising agent?

Answer 7

Something that accepts electrons and gets reduced

Question 8

What is an reducing agent?

Answer 8

Something that donates electrons and gets oxidised

Question 9

How does a barrier method work?

Answer 9

Coating the metal with paint or oil to prevent rust

Question 10

How does galvanising work?

Answer 10

Covering the metal with zinc as zinc is more reactive than Iron so therefore it will be oxidised instead of the Iron
