Hydrophilic gels, when placed in water, ...

Hydrophilic gels, when placed in water, absorb liquid resulting in an increase of their volume. This process of swelling of gels takes place with:

A

No change of volume

B

Net increase of volume

C

Net decrease of volume

D

Large reduction in volume

Text Solution

Verified by Experts

Hydrophilic gels possesses rigid structure formed due to interlocking of particles of disperse phase and create a loose frame work. The particles of dispersion medium are trapped into the loose framework. Hence overall process takes place with decrease is volume.
