Connect 14 November, 2018 Metal Oxides Key Words Oxide Acid Alkali Neutralisation Salt 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 = 1.......... 2....... 3........ Non-metals = 1...... 2..... 3........ Challenge: Describe the properties that all metals have in common. 1

Metal Oxides Lesson Outcomes: Connect 14 November, 2018 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

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)

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

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

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
