The correct answer is D) colloidal solution of two liquids. An emulsion is a specific type of colloid where one liquid is dispersed throughout another liquid in the form of tiny droplets. The two liquids are typically immiscible or poorly miscible.
– Emulsions are colloidal systems.
– The dispersed phase and the dispersion medium are both liquids.
– Examples include milk (fat droplets dispersed in water) and mayonnaise (oil dispersed in vinegar).
– Colloidal solutions can involve different physical states (e.g., solid in gas for smoke, liquid in gas for fog), but an emulsion is specifically liquid in liquid.
– A true solution is a homogeneous mixture where the solute is dissolved at the molecular or ionic level, unlike a colloid which has larger dispersed particles.
– Distillation is a separation technique, not a type of solution or mixture in this context.
