Quick explanation

Link electrical conductivity in ionic compounds to ions that are free to move

  • This point belongs to How bonding and structure are related to the properties of substances, especially Properties of ionic compounds.
  • You need to be able to link electrical conductivity in ionic compounds to ions that are free to move.
  • The key ideas to know are ionic compound.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect Properties of ionic compounds to exam-style questions, flashcards, and revision notes for How bonding and structure are related to the properties of substances.

Quick student answer

What should you know about electrical conductivity in ionic compounds to ions that are free to move?

Direct answer

In Chemistry, this page helps you answer questions about electrical conductivity in ionic compounds to ions that are free to move within How bonding and structure are related to the properties of substances. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are ionic compound and free-moving ions.

Key terms

  • ionic compound: In Properties of ionic compounds, ionic compound means a compound formed from the electrostatic attraction between oppositely charged ions. This matters in How bonding and structure are related to the properties of substances because it supports the learning objective to link electrical conductivity in ionic compounds to ions that are free to move. Use ionic compound only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
  • free-moving ions: Ions that are not fixed in place and can move freely, allowing for electrical conductivity.

Common trap

Misunderstanding Ionic Conductivity: Explain that ionic compounds only conduct electricity when they are molten or dissolved in water, as this is when ions are free to move.
