Question

Why are lyophillic colloidal sols are more stable than lyophobic colloidal sol?

Answer 1

1. A lyophillic colloidal sols are stable due to the charge and the hydration of sol particles.

2. Lyophillic sols are more stable than lyophobic sols because they are highly hydrated in the solution. And since more is the hydration more will be its stability.

3. Lyophillic sols are stabilized by electrostatic charge and hydration whereas lyophobic sols are only stabilized by charge, so they easily get coagulated and require a stabilising agent. Hence, lyophillic sols are more stable than lyophobic sols.
