Which one of the following statement is not correct?
Options
- AA mixture of dinitrogen and dioxygen at room temperature is an example for aerosol
- BLyophilic sols are more stable compared to lyophobic sols
- CFormation of micelles is possible only above Kraft temperature
- DAn example for a soap is sodium stearate and an example for detergent is sodium lauryl sulphate
Correct answer
A. A mixture of dinitrogen and dioxygen at room temperature is an example for aerosol
Step-by-step solution
(a) A mixture of N2 and O2 gases at room tem per a ture form gases mixture but do not form aero sol. (b) Lyophobic sol is least stable than lyophilic. (c) Micelle is obtain at or over the Kraft temperature. (d) Detergents like sodium lauryl sulphate and soap are like sodium sterate.
