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
