Question

Surface tension of lyophilic sols is.

• A. Lower than that of $\mathrm { H } _ { 2 } \mathrm { O }$
• B. More than that of $\mathrm { H } _ { 2 } \mathrm { O }$
• C. Equal to that of $\mathrm { H } _ { 2 } \mathrm { O }$
• D. None of these

Answer 1

Answer: (A)

Lower than that of $\mathrm { H } _ { 2 } \mathrm { O }$

Answer 2

Surface tension of lyophilic sol is lower than that of the dispersion medium (i.e.$\mathrm { H } _ { 2 } \mathrm { O }$ in this case.)
