SHinosoyy bo namunahoi sulfur va payvastagihoi on

1. Namunahoi sulfur va payvastagihoi onro, ki az muallim gi- riftaed, muoina kuned. Dar daftar az ruyi tartibi zerin navi- sed: Nom; 2. Formulai khimiyavi; 3. Holati agregati; 4. Rang; 5. Sakhti.
2. Istehsoli ozon va khosiyathoi on

Istehsoli ozon. a) Az asbobe, ki dar rasmi 21 inikos shuda- ast, istifoda burda ozon hosil kuned. b) Ba yak probirka kame pe- roksidi bariyi VaO₂ khokamonand andozed va ba probirkai digar 2 ml kislotai sulfati konsentronida rezed.

Ravand bo muodilai zerin ifoda meshavad: 3VaO₂ + 3N₂😯₄  3Va8O₄; + 3N₂O + O₃$

Hosiyathoi ozon. Dar har du tajriba ozoni hosilshudaro az buyi khosash his me- kunand. Ozonro inchunin bo istifodai khosiyathoi khubi oksidkunandagiash muayyan kardan mumkin ast. Ba in tavr: a) kogazi lak- musi kabud yo surkhi dar ob tar kardashudaro dar boloi probirkae, ki az on ozon khorijHar du probirkaro ba zarfi obi khunuk (yo omekhtai khunukkunan- da iborat az barfu khloridi natriy) guzoshta sard kuned. Sipas kislotai sulfatro ba probirkai peroksidi bariy rekhta, bo qalamchai shishagi omekhta namuda dar yak vaqt khunuk kuned.

meshavad, nigoh dored; b) porchai kogazi poloish (filtr)-ro, ki dar mahluli yodidi kaliy va shireshi krakhmal tar karda shuda- ast, dar jarayoni ozon guzored.

Muodilai reaksiyai ozon bo yodidi kaliy chunin ast:

2K1 + O₃ + N₂O     2KON + .1, +O₂$

Suporish. 1. Berang shudani kogazi lakmus dar borai kadom khosiyathoi ozon shahodat medihad? 2. CHaro dar tajribai okhirin rangi kabud paydo shud?
