Consider the following surfactants:
(a) Which are nonionic surfactants?
i) A
ii) B
iii)C
iv) D
v) E
not right
OOOOO SORRY B AND E
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?
a B E
b B E
c E
d critical micelle concentration
e I have no idea
(e). Region B
(f). 0
Thank you.
(a) B E
