Question
Match the following Columns:<br>Column I (Colloidal solution):<br>(A) Collodion<br>(B) Fog<br>(C) Butter<br>(D) Milk<br><br>Column II (Dispersed phase):<br>(P) Water<br>(Q) Cellulose<br>(R) Fat<br>(X) Water<br><br>Column III (Dispersion medium):<br>(U) Ethanol<br>(V) Oil<br>(W) Air
Answer: A→Q,U; B→P,W; C→P,V; D→R,X
💡 Solution & Explanation
(A) Collodion: nitrocellulose (Q=Cellulose) dispersed in ethanol (U=Ethanol). (B) Fog: liquid water droplets (P=Water) dispersed in air (W=Air). (C) Butter: water-in-oil emulsion — water (P) dispersed in fat/oil (V=Oil). (D) Milk: oil-in-water emulsion — fat globules (R=Fat) dispersed in water (X=Water). Answer: A$\to$Q,U; B$\to$P,W; C$\to$P,V; D$\to$R,X
