Problem

An aqueous solution of XX is added slowly to an aqueous solution of YY as shown in List I. Match the variation in conductivity in List II and select the correct code. Column I — P: X: (CX2HX5)3N;Y:CHX3COOHX:\ (\ce{C2H5})3N;\quad Y:\ce{CH3COOH}; Q: X: KI(0.1 M);Y: AgNOX3(0.01 M)X:\ \ce{KI}(0.1\,\mathrm M);\quad Y:\ \ce{AgNO3}(0.01\,\mathrm M); R: X: CHX3COOH;Y: KOHX:\ \ce{CH3COOH};\quad Y:\ \ce{KOH}; S: X: NaOH;Y: HIX:\ \ce{NaOH};\quad Y:\ \ce{HI} Column Ii — 1: Conductivity decreases and then increases; 2: Conductivity decreases and then does not change much; 3: Conductivity increases and then does not change much; 4: Conductivity does not change much and then increases
