Consider the following surfactants:

(a) Which are nonionic surfactants?

i) A
ii) B
iii)C
iv) D
v) E

  • Chemistry -

    not right

  • Chemistry -

    OOOOO SORRY B AND E

  • Chemistry -

    Thank you for a)

    Any ideas for

    (b) Which are likely to have much lower critical micelle concentrations?
    A
    B
    C
    D
    E

    (c) Which surfactant is more likely to form non-spherical micelles?
    A
    B
    C
    D
    E

    The surface tension versus concentration for a surfactant in aqueous solution is shown below. The surface tension versus concentration naturally divides into two different regions, A and B.

    (d) What phenomena divides region A from B?
    i)Critical micelle concentration
    ii)Intermolecular Bond Strength

    (e) You wish to use a solution of this surfactant in water to dissolve oil. Which region will be required to do this?
    i)Region A
    ii)Region B

    (f) How much oil will dissolve in the surfactant-water solution if the concentration of surfactant falls in region A?

  • Chemistry -

    a B E
    b B E
    c E
    d critical micelle concentration
    e I have no idea

  • Chemistry -

    (e). Region B
    (f). 0

    Thank you.
    (a) B E
    (b) B E
    (c) E
    (d) critical micelle concentration
    (e). Region B
    (f). 0
