JEE Main Chemistry question

Not in JEE Main or NEET syllabus

The false statement for hydrophilic sols is:

(A)They do not require electrolytes for stability
(B)Coagulation is reversible
(C)Viscosity is of the order of that of waterCorrect
(D)Surface tension is lower than that of the dispersion medium

Answer: (C)

Solution

Hydrophilic sols are stabilised by extensive solvation rather than charge, so they indeed do not require electrolytes for stability, are reversibly coagulated, and have lower surface tension than the medium; however, their
