MAVZU: VODORODNING OLINISHI.
5-LABORATORIYA ISHI: KISLOTA ERITMASIGA RUX TA'SIR ЕТТIRIB VODOROD OLISH.
Maqsad: o'quvchilarni oddiy asboblarni tuzishga va bu asboblardan vodorod olishga o'rgatish.
Jihozlar: polipropilen stakan 150 ml li (1), shisha stakan (2), polipropilen stakan 50 ml li (3), yuvgich (4), qisqich (5), shisha tayoqcha (6), plastmassa shpatel (7), probirka (8), probirkalar uchun shtativ (9), pipetka (10), plastik taglik (11), gazlar olish asbobi, laboratoriya shtativi.
Reaktivlar: xlorid kislota eritmasi (1:1), rux granulasi.
O'quv-ko'rgazmali qo'llanmalar: «Kimyo fanidan proyeksion ko'rgazmali metodik qollanmalar», 57-bet.
E ritma tayyorlash: xlorid kisiotaning 1:1 nisbatdagi eritmasini tayyorlash uchun 100 ml li polipropilen silindrning 50 ml belgisigacha distillangan suv quyiladi va ustiga 100 ml belgisigacha xlorid kisiotaning konsentrlangan eritmasidan ohistalik bilan quyiladi va shisha tayoqcha bilan aralashtiriladi.

Jihozlar to'plami Laboratoriya shtativi gaz olish asbobi

Ishni bajarish tartibi:

1. 
   Gaz olish asbobi laboratoriya shtativiga o'rnatiladi.
   

1. 
   Rux granulalarini rezina vtulka ustiga qo'yib probirkaga joylashtiriladi, voronka orqali sulfat kislota eritmasi quyiladi.
   

3. 
   Ajralib chihayotgan gazni og'zi pastga qaratilgan probirkaga shisha nay uchini to'g'rilab yig'iladi.
   
4. 
   Vodorod ekanini isbotlash uchun nay uchidan ajralib chiqayotgan gaz yoqiladi.
