Question

Nonionic surfactants and polymers show cloud point phenomena when dissolved in water. The cloud point represents the temperature:

Above which nonionic surfactants precipitate

Below which nonionic surfactant precipitates

Above which nonionic surfactants form spherical micelles

Below which nonionic surfactants form lamelllar phase

Above which nonionic surfactants precipitate

Below which nonionic surfactant precipitates

Above which nonionic surfactants form spherical micelles

Below which nonionic surfactants form lamelllar phase

Explanation / Answer

Anwer

a) Above which nonionic surfactants precipitate

Explanation

Surfactants is made up of polar head groups(hydrophilic) and non polar tailgroup(hydrophobic).The polar groups are be cationic, anionic or nonionic,non polar groups are hydrocarbon, flourocarbon or a siloxane.

Surfactants undergo phase transition above particular temperature, so the surfactant solution become cloudy and this is called cloud point.
