DISPLACEMENT REACTIONS

Instructions1. Care! You should wear GOGGLES and LAB-COATS at

all times during this practical2. Obtain a dropping tile3. Add a few drops of each of the solutions to

individual ‘holes’ in the dropping tile. Make sure you know which solution is which

4. Choose a metal5. Add one piece of that metal to each of the solutions6. Observe – you will need to watch carefully for any

evidence of a reaction taking place7. If a reaction takes place, put a tick into the relevant

box. If no reaction takes place, put a cross.8. If a reaction takes place, try and describe what is

happening9. Wash all the reactions into a large beaker – do NOT

put any solids into the sink!10. Repeat for each metal using fresh solutions
