LO: I can describe the reactions of different oxides
Starter: Your periodic table contains the name of all the chemical elements. Use it to write the names on THREE metals and THREE non-metal elements
Metals =
Non-metals =
Challenge: Describe the properties that all metals have in common. 1

Metal Oxides
Key Words
Oxide
Acid
Alkali
Neutralisation
Salt
LO: To understand the formation and reactions of metal and non-metal oxides
Lesson Outcomes:
B to 1
I can recognise and name some examples of metal and non-metal oxides 2
I can state how oxides are formed 3
I can describe how oxides from metals and non metals have different properties. 4
I can explain the reactions of oxides using word (and Symbol equations - H only).
5 - 6
I can consider the environmental impacts of non-metals oxides in the atmosphere on our environment 2

3. An oxide is formed when an element reacts with oxygen in the air.
What is an oxide?
An oxide is formed when an element reacts with oxygen in the air.
Elements are found on the periodic table.
OXIDE
OXYGEN
Iron + oxygen --> Iron oxide
Challenge: Write word equations for the formation of copper oxide, zinc oxide and magnesium oxide.(Think about last lesson)

4. Non metal oxides form acidic solution
What is an oxide?
Oxides are often solids or gases but they can be acidic or alkaline when dissolved in water
Non metal oxides form acidic solution
Metal oxides form alkaline solutions.
Metal oxides (Bases) can be used to neutralise acids.
Acid + Metal oxide  Salt + Water
Acid + Base  Salt + Water

5. Colour of Universal indicator
Practical
To test this you are going to add metal oxides to water and see what happens to the pH.
Copy the table and record your results
Name of Oxide
Colour of Universal indicator
pH Value
Acid, Alkali or Neutral
Exploring science Year 9 9Gb2 Practical Sheet ‘Oxides’
Challenge: Can you suggest another way we could test if a metal oxide was acidic or alkaline? 5

7. 2] Carbon oxide and water 3] Zinc oxide and hydrochloric acid
Mini Plenary
Describe and explain the resulting pH of these reactions. Acid, alkaline or neutral?
1] Iron oxide and water
2] Carbon oxide and water
3] Zinc oxide and hydrochloric acid
4] Zinc oxide and sodium hydroxide
Metal oxides (Bases) can be used to neutralise acids.
Acid + Metal oxide  Salt + Water
Acid + Base  Salt + Water
Challenge: Write a word equation for reaction 3.
Write a symbol equation for reaction 3 7
