Why does cooking oil react with water?
Water and oil do not mix. They are said to be immiscible. This is because water is a polar molecule – its structure means that is has a positive charge one end and a negative charge the other end. Water molecules stick together because the positive end of one water molecule is attracted to the negative end of another.
