  1. S – Sulphur By Hana Guryčová & Eliška Chytilová

  2. The essentials • Name: Sulphur • Symbol: S • Atomic number: 16 • Group number: 16 (IV.A) • Group name: Chalcogen • Period number: 3 • Electron configuration: [Ne] 3s2 3p4 1s2 2s2 2p6 3s2 3p4 The Essentials – základní informace

  3. Description • Here is a brief description of sulphur: • Standard state: Solid • Melting point:115,21°C • Boiling point:444,72°C • Colour: Lemon yellow • Classification: Non-metallic Description – popis

  4. Allotrope of sulphur • Rhombic sulphur • Prismatic sulphur • Liquid sulphur and brown vapours • Sulphur flowers • Plastic sulphur Allotrope – alotropické modifikace Rhombic - kosočtverečná Prismatic - jednoklonná

  5. Distribution 1. Elementary sulphur: volcanic activity hot springs

  6. Distribution 2. Compounds: sphalerite ZnS pyrite FeS2 cinnabar HgS galenite PbS

  7. Application 1.In ancient time (China) – component of gunpowder 2. At the present time – fireworks – vulcanisation – manufacture of sulphuric acid – battery – fungicide Gunpowder- střelný prach Fireworks- zábavní pyrotechnika Fungicide- prostředky působící proti růstu hub a plísní

  8. Biologicalrole • Sulfur is an important component of: • amino acids cysteine and methionine • polypeptides, proteins, enzymes • coenzyme A • Some forms of bacteria use hydrogen sulfide (H2S)

  9. Environmental Impact Burning of coal and petroleum sulfur dioxide SO2 atmospheric water and oxygen sulfuric acid = acid rain !lowers the pH of soil and freshwater bodies!

  10. Reaction of sulphur For Example: Sulphur burns in air to form the gaseous dioxide sulphurdioxide, SO2 S8(s) + 8O2(g) ––>8SO2(s) Others: • H2S + I2 ––> S + 2HI • SO2 + 2CO ––> S + 2CO2 • CuO + H2SO4––> CuSO4 + H2O • Zn + H2SO4––> ZnSO4 + H2 • SO3 + H2O ––> H2SO4 • MgSO3––> MgO+ SO2

  11. Thank you very much for your kind attention
