Surfactants are the substances which show surface activity .Detergents possess surface activtiy as wll as detergency . Soaps are anionic class of detergents . It is the hydorphilic part of detergent momencule which possesses the tendecy to attract water moleculse wheras hydrophilic blances part orients away from waer . The hydrophilic-lipphilic balance (HLB) leads to affergation of anooic or non-ionic or cationci part of detergent to form icellse . Each molecule has the defintie concentration at defintie temperature at which it states to aggrater . It is due to teh presence of two moities in their molecules, surffactants stabilize emulision ( a water -oil system ) . Due to larger surface area, the mediacines are more effective in emulion form . Emulisons are ` w//o or o //w type`. A water soluble dye imparts its collour to ` o//w` emulsions.
Select the correct statements .
I. In multimolecular collidal solutiobatoms of momecules are held togenther by va der Waaks' forces
Cleansing action of soap is due to adsorption of iliy and gresy material at hydrophilic centres
III. Hydorphilic part of oily and greasy materical at hydrophilic centres
IV. The aggergation of ions i.e., micelle formation is independt of temeratrue .
