320777 Which substance is not used for preparing lyophilic sols?

1 Starch
2 Gum
3 Gelatin
4 Metal sulphide
CHXII05:SURFACE CHEMISTRY

320778 Assertion :
Lyophilic sols are very stable.
Reason :
In these sols, much affinity exists between the disperse phase and the dispersion medium.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

320779 Assertion :
Gold sol is a lyophobic sol
Reason :
In gold sol there is less affinity between gold particle and water.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

320780 Lyophilic sols are more stable than lyphobic sols because

1 The colloidal particles have positive charge
2 The colloidal particles have negative charge
3 The colloidal particles are solvated
4 There are strong electrostatic repulsions between the negatively charged colloidal particles
