Important Compounds of Transition Elements
Introduction to Transition Elements
Transition elements are d-block elements that form various compounds with unique properties.
They exhibit variable oxidation states, form colored compounds, and are essential in many industrial
and biological processes.
Common Oxides and Hydroxides
1. Iron Oxides (Fe2O3, Fe3O4): Used in pigments and magnetic materials.
2. Chromium Oxide (Cr2O3): A green pigment and corrosion-resistant material.
3. Copper Hydroxide (Cu(OH)2): Used as a fungicide and in electroplating.
Complex Compounds
1. Potassium Ferricyanide ([Fe(CN)6]3-): Used in blueprints and as an analytical reagent.
2. Tetraamminecopper(II) Sulfate ([Cu(NH3)4]2+): A deep blue complex used in qualitative analysis.
3. Cisplatin (Pt(NH3)2Cl2): A platinum-based anticancer drug.
Industrial and Biological Importance
- Hemoglobin (Fe complex) helps transport oxygen in blood.
- Vitamin B12 contains cobalt and is essential for metabolism.
- Nickel and Platinum complexes are used as catalysts in industries.
Uses of These Compounds
- Transition metal oxides are used in batteries and ceramics.
- Complexes like silver nitrate (AgNO3) are used in photography.
- Titanium dioxide (TiO2) is used in sunscreens and paints.
