Why this why now

This unit builds on pupils’ prior learning from Understanding chemical reactions, where they explored how substances interact and transform during chemical processes. It deepens their understanding by examining the properties of acids and bases, their reactions, and the concept of pH. This prepares pupils for the next unit, Making salts, where they will apply their knowledge of acid-base reactions to create different salts, reinforcing the practical application of chemical reactions and enhancing their understanding of chemical processes.

Prior knowledge requirements

  • Some solids can dissolve to form solutions.
  • New materials are formed as a result of a chemical reaction.
  • One group (or class) of chemical substances is called acids.
  • In a chemical reaction, atoms rearrange themselves to form new substances
  • Word equations are a simple way of describing chemical reactions
