Questions and Answers

How does the hydrophobic 'tail' of soap behave at the surface of water?

It aligns along the surface of water with the ionic end in water and the hydrocarbon 'tail' protruding out of water.

What are the two differing properties of soap molecules?

One end is hydrophilic (interacts with water) and the other end is hydrophobic (interacts with hydrocarbons).

What is the unique orientation of soap molecules inside water that keeps the hydrocarbon portion out of the water?

Clusters of molecules in which the hydrophobic tails are in the interior of the cluster and the ionic ends are on the surface of the cluster.

What is the formation called when soap molecules arrange themselves in clusters with the hydrophobic tails in the interior and the ionic ends on the surface?
