5. Experiment
Aim: To find out about the removal of stains from fabric using knowledge of solubility.
Method:
Collect a small beaker.
Add stained fabric and enough solvent to cover stained fabric.
Stir fabric and solvent.
Decide if stain is being removed (i.e. if it is soluble or insoluble in this solvent).
Record in the table.
Repeat for the other stains.
