Watch each video then attempt the following:

  • record any observations made during the reaction
  • Explain how the observations for each reaction relates to the species involved
  • Write balanced half and overall reactions

Hand in your work tomorrow for checking. At the very least you should be able to complete the observations

(1) A redox reaction between copper metal and 50% nitric acid containing nitrate ions

(2) A redox reaction between chlorine and and iron(II) ions

(3)Redox reaction between dichromate ions and sulphite ions.

(4) A redox reaction between chlorine and iodide ions
