Question

if you add oil to the water, what will happen? will it create a single homogeneous phase or will it form two layers​

Answer 1

it will form two layers

Answer 2

What will happen if you add oil to the water:

• The water molecules are attracted to one another, whereas the oil molecules cling to one another. As a result, oil and water split into two layers. Because water molecules are closer together, they sink to the bottom, leaving oil floating on top.

• Water molecules have a polar shape. That indicates the molecule has a positive charge on one end and a negative charge on the other. Water molecules are able to bind together as a result of this. On the other hand, oil molecules are non-polar.

• Non-polar molecules, on the other hand, only mix well with other non-polar molecules. This explains why oil and water don't mix. Their molecules are incapable of forming bonds.

• Oil and water can be mixed for extended lengths of time. All you have to do now is add an emulsifier. That's a molecule having one polar and one non-polar end on one end. Egg yolks are frequently used as emulsifiers. So, also, is soap! On one end, it draws oil, while on the other, it attracts water. That's what actually happens when we use soap to clean our hands.
