topic 6: chemical reactions

• Describe the distinctive features of metals
• Recognise exceptions to patterns
•  Understand that salts are made of positive and negative ions. Positive ions are mostly metals, negative ions can be halides (chloride), nitrate, or sulphate depending on the acid used to prepare the salt.
• Provide evidence for links between properties and uses
• Neutralise an acid
• Recognise the reaction of acids with metals producing salt and hydrogen (done in previous chapter, revisit to emphasise on the production of salt).
• Explain the relationship between bases and alkalis
• Use the patterns of reactions to write neutralisation reactions
• Use tests to identify chemicals
• Recognise that hydrochloric acid produces chlorides, nitric acid produces nitrates and sulphuric acid produces sulphates.
• Analyse evidence that the mass may change during reactions
• Use a particle model to explain why reaction speeds change
• Explain what a salt is
• Describe the general salt preparations
• Interpret the formulae of salts
• Understand how neutralisation reactions produce salts
• Recognise the reaction of acids with carbonates producing salt water and carbon dioxide.
• How to write equations to summarise reactions
• Devise and carry out a salt preparation
• Study the rate of a reaction using carbonate and acid.
• Explain what precipitation is
• Understand how precipitation can be used to make salts
• Learn the crystallisation process and that bigger crystals are obtained when evaporation happen slowly.
• Recognise the commercial importance of precipitation
• Use separation methods based on chemical and physical properties
• Explain how processes can be used to produce useful materials
• Plan a multi-stage procedure to purify a substance
• Explain how catalysts work. Observe the catalytic decomposition of hydrogen peroxide to give water and oxygen using manganese dioxide as a catalyst.
• Learn about the thermal decomposition of carbonates to produce oxides and carbon dioxide.
