Describe some features of catalysis by zeolites.
(i) Medicines are more effective in their colloidal form.
(ii) Lyophilic colloids are more stable than lyophobic colloids.

Lyophilic sols are more stable than lyophobic sols because

Why lyophilic colloidal sols are more stable than lyophobic colloidal sols ?

Why are some medicines more effective in the colloidal form?

Why are some medicines more effective in the colloidal form ?

How do you account for the following: Medicines are more effective in their colloidal form.

A lyophobic colloid cannot be formed by

A : Lyophillic sols are mors stable than lyophobic sols. R : Lyophilic sols are more readily hydrated than lyphobic sols

Differentiate between lyophilic and lyophobic colloids.

In each of the following pairs of ions in which I ion is more stable than II

Give reason for the following observations : (i) When Silver nitrate solution is added to Potassium iodide soltuion , a negatively charge colloidal solution is formed. (ii) Finely divided substance is more effective as an adsorbent. (iii) Lyophilic colloid are also called reversible sols.
