Question

give two point of difference between lyophetic and lyophobic colloids
​

Answer 1

Lyophilic : Reversible, because on evaporating the liquid, the residue left will passes into colloidal state on addition of liquid. Lyophobic : Irreversible, because on evaporating the liquid, the residue left cannot be converted into solution on mere addition of liquid.

Answer 2

Lyophilic : Reversible, because on evaporating the liquid, the residue left will passes into colloidal state on addition of liquid.

 Lyophobic : Irreversible, because on evaporating the liquid, the residue left cannot be converted into solution on mere addition of liquid.
