Anionic surfactants are

10 ml of 1 millimolar surfactant solution forms a monolayer covering 0.24cm^(2) on a polar substrate. If the polar head is approximated as a cube. Consider the surfactant is adsorbed only on one face of the cube. What is the edge length of cube? (Answer should be in pm and assume Avogadro's number =6xx10^(23) ).

In alveoli, surfactant is produced by

Lack of pulmonary surfactant produces

At the critical micelle concentration, the surfactant molecules

At the critical micelle concentration, the surfactant molecules :

Assertion (A): Micelles are formed by surfactant molecules above the critical micellization concentration (CMC) . Reason(R): The conductivity of a solution having surfactant molecules decreases sharply at the CMC .

Molecules from 10mL of 1mM surfactant solution are adsorbed on 0.24cm^(2) area forming unimolecular layer. Assuming surfactant molecules to be cube in shape, determine the edge length of the cube.

The following are the two statements regarding alveolar fluid: (a) It contains a surfactant that reduces the tendency of alveoli to collapse. (b) Surfactant in the alveolar fluid lowers the surface tension. Of the above statements, which one of the following options is correct?

Among the following, the surfactant that will form micelles in aqueous solution at the lowest molar concentration at ambient condition is
