LABORATORIYA ISHI № 1.

Sana:_____________


Mavzu: Ifloslangan osh tuzini tozalash.
Ishning maqsadi: Laboratoriya sharoitida ifloslangan osh tuzini tozalash.
Asboblar: Spirt lampasi, havoncha, shtativ, filtr qog’ozi. KSL-1083, KSL-114, KSL-1041-1
Reaktivlar: Osh tuzi, qum tuproq.
Ishning mazmuni:Agarosh tuzi qum yoki tuproq bilan ifloslangan bo’lsa, uni birinchi suvga solib eritamiz va filtrlaymiz. Qum bo'lsa tindiramiz. Filtrlanganda yoki tindirilganda, qum yoki tuproq osh tuzi eritmasidan ajratitib olinadi. Erigan osh tuzini eritmadan ajratib olish uchun eritma bug'latiladi va suv bug'lanib, ancha konsentrlangan eritma bosil bo'ladi, bu eritma sovutilganda erigan modda kristallar holida ajralib chiqadi.
Demak, biz ifloslangan osh tuzini tozalashda filtrlash, tindirish va kristallash usullaridan foydalandik,
Agar osh tuzimagnitga tortiladigan moddalar bilan ifloslangan bo’lsа, aralashmaga magnit ta'sir etamiz va temir yoki shunga o'xshash magnitlanadigan moddalarni oshtuzidan ajratib olamiz. Bulardan tashqari osh tuzini qog'oz, paraxa va shunga o'xshash suvga cho'kmaydigan narsalar bilan itioslanganda ftotasiya usulidan foydalanamiz.
