Question
Why soap solution appears cloudy?

Answer

Soap is mixed with water to form micelle which gives the solution a cloudy appearance when soap is added to the water the fatty acid ionizes. The polar water soluble gets attracted to water while the non-polar tails attract each other. Then the ions are attracted to each other and form the special clusters and sometimes in a form of emulsions which gives a cloudy look.
