Answer» Solution :In PREPARATION of alloys, currency coins, statues, utensils etc. Ex: ..JK.. coins are Cu-Ni alloy. Alloy like Hg -amalgam is used in dentistry. The iron and steels are most important construction materials. Their production is based on the reduction of iron oxides. Mercruy is used in thermometer GOLD and copper alloys is used in preparation of ornaments Transition elements and their compounds are used as catalyst in VARIOUS chemical reactions Ex: Ni in hydrogenation of fats, `PdCl_(2)` in wacker.s process `V_(2)O_(5)` in contact process. `TiCl_(4)` in polymerisation of polythene along with `Al(C_(2)H_(5))_(3)`, Fe in Haber.s process etc. The complexes of Ni is used in polymerisation of alkynes and other organic compounds such as benzene. Zn is used in galvanization `MnO_(2)` is used in dry cell. Ni and Cd are used in BATTERIES AgBr is used in photography DUE to its light sensitive property TiO is used in pigment industry ZnS in preparation of lithophone Pd and Pt are used as electrodes. `Hg_(2)Cl_(2)` is used as reference electrons (calomel electrodes) |
