Compositions of nominal formula, AgI 1− x Cl x ( x =0–0.25) were prepared by soft chemical method. The synthesized compositions were characterized by various physicochemical techniques. The studies revealed the formation of solid solution of AgCl in AgI up to 5 mol %. The composition AgI 0.95 Cl 0.05 exhibited marginally higher conductivity than AgI. Electrochemical sensors were assembled using AgI and AgI 0.95 Cl 0.05 . Iodine sensing properties of these two potentiometric sensors were elucidated. Preliminary results show that I 2 can be sensed down to ∼10 vppm.
