Visual Mark Scheme Breakdown

• Where do copper and potassium sit in the reactivity series?

  • Potassium is at the top (very reactive)

  • Copper is at the bottom, below hydrogen

• What does this mean about their reactivity with acid? (2 mark)

  • Potassium is dangerously reactive. (1 mark)

  • Copper is under hydrogen in the series so does NOT react with dilute acid. (1 mark)
