The qualitative sketches I, II and III given below show the variation of surface tension with molar concentration of three different aqueous solutions KCl, CH3OH and CH3(CH2)11OSO3–Na+ at room temperature. The correct assignment of the sketches is
- I : KCl
II : CH3OHIII : CH3(CH2)11OSO3–Na+ - I : CH3(CH2)11OSO3–Na+
II : CH3OHIII : KCl - I : KCl
II : CH3(CH2)11OSO3–Na+ III : CH3OH - I : CH3OH
II : KClIII : CH3(CH2)11OSO3–Na+
Answer
(C) I : KCl II : CH 3 (CH 2 ) 11 OSO 3 – Na + III : CH 3 OH
