Applications of d- and f- Block Elements Flashcards
What are the most important construction materials?
Iron and steel
Their production is based on the reduction of iron oxides, removal of impurities, and the addition of carbon and alloying metals such as Cr, Mn, and Ni.
What is TiO used for?
Pigment industry
TiO is a crucial component in the production of pigments.
What elements are used in the preparation of dry battery cells?
Manganese dioxide (MnO2) and Zinc
These elements are key components in dry batteries.
Which elements are referred to as ‘Coinage Elements’?
Elements of Group-11
These elements are considered precious and include silver (Ag) and gold (Au).
What are contemporary UK copper coins made of?
Copper-coated steel
The silver UK coins are made of a Cu/Ni alloy.
What is the role of transition elements and their compounds in the chemical industry?
Essential catalysts
They are vital for various chemical processes.
What does V2O5 catalyze in the manufacture of sulfuric acid?
The oxidation of SO2 to SO3
This reaction is crucial for sulfuric acid production.
What are Zieglar-Natta catalysts used for?
Manufacturing polythene
They are based on TiCl4 with Al(CH3)3.
What catalyst is used in Haber’s process for ammonia production?
Iron catalyst
This process involves nitrogen (N2) and hydrogen (H2) mixtures.
What do nickel catalysts enable?
Hydrogenation of fats
Nickel is used to facilitate the hydrogenation process.
What does PdCl2 catalyze in Wacker’s process?
