Learn why some liquids do not mix with each other
RN: 10112903 - CHEMISTRY > CHEMICAL ANALYSIS
3 & 4
Not all liquids can be mixed together to form one new liquid substance. If more than one liquid cannot be mixed together it is called 'immiscible' liquids. In this science experiment we will investigate the strange behaviour of some of these 'immiscible' liquids:
STUFF YOU NEED [MATERIALS]
- FOOD COLOURING
- TAP WATER
- RUBBING ALCOHOL
- COOKING OIL
- DISHWASHING LIQUID
- 2x GLASS JARS
HOW TO PROCEED [PROCEDURE]
- Fill a medium sized glass jar about ¼ full with water.
- Gently add about the same amount of cooking oil to the water by tipping the jar slightly and pouring it against the side of the jar.
- Now gently add some rubbing alcohol to the 'mixture' in the same fashion that you did with the oil and notice how these three liquids do not mix with each other, and lies in layers on top of each other.
