उत्तर
Among lyophilic and lyophobic sols, lyophilic sols are more stable.
Explanation:
Lyophilic sols are stable because they are heavily hydrated and self-stabilized, which prevents their particles from coagulating easily. They do not require stabilizing agents and are reversible, meaning the dispersed phase can be redispersed by simply mixing with the dispersion medium. Lyophobic sols are less stable, easily coagulated by heat, agitation, or electrolytes, and need stabilizers to remain in the sol state longer.
