Critical micelle concentration (CMC) values of surfactants in different experimental conditions.

Solutions	10^4, CTAB mol dm^−3	10^3, SDS mol dm^−3
(i) Water	10.3	9.15
(ii) Fructose	9.42	5.23
(iii) NBS	9.90	9.45
(iv) Acetic acid (v/v)	9.0	2.26
(v) H2SO4	8.20	1.57
(vi) Fructose + NBS + acetic acid% (v/v) + H2SO4	3.90	4.92

Reaction conditions: fructose = 2.5 10⁻² mol dm⁻³, [NBS] = 2.0 10⁻⁴ mol dm⁻³, Hg(OAc)₂ = 5.0 10⁻⁴ mol dm⁻³, [H₂SO₄] = 0.5 10⁻⁴ mol dm⁻³, and acetic acid (30% (v/v)). Literature value at 25°C cmc of CTAB is 9.2 10⁻⁴ mol dm⁻³; SDS is 8.3 10⁻³ mol dm⁻³.
