Are egg shells acid or alkali?

  • Egg shells are made of calcium carbonate
  • We can test whether this dissolves the shell in a neutralisation reaction
  • You are going to:
    • Decorate a raw egg using wax crayons (only the exposed bits will react so think carefully about your design so your egg stays egg shaped after the reaction)
    • Place your egg in a plastic cup with vinegar
  • What happened? Write a conclusion answering the question above
