15-Laboratoriya ishi: MIS VA ТЕМR(II)-GIDROKSIDLARNI HOSIL QILISH.
Maqsad: suvda erimaydigan asoslarni hosil qilish va ularni indikatorlarga ta'sirini o'rgani.
Jihozlar: 150 ml li polipropilen stakan (1), tomchi analizi uchun to'plam (2), probirka! uchun shtativ (3), probirkalar (4), shisha tayoqcha (5), shpatel (6), tomchi analizi uchi planshet (7), plastik taglik (8), indikator qog'ozi (9), shishaga yozish uchun qalam (1 shisha stakan( 11).
R eaktivlar: mis (II) sulfat CuS0₄, temir (II) sulfat (Mor tuzi), distillangan suv, nat ishqori NaOH.
O'quv-ko'rgazmali qurollar: «Kimyo fanidan proeksion ko'rgazmali-metodikqo'llanmalar», 54-bet Jihozlar to'plami
Avtomatik mikropipetka
Ishni bajarish tartibi:

1. 
   Ikkita probirkaning biriga mis sulfat CuS0₄ eritmasi, ikkinchisiga Mor tuzi eritmasi pipetka bilan 3-4 tomchi tomiziladi.
   
2. 
   Ikkala probirkaga ham pipetka yordamida natriy gidroksidi NaOH eritmasidan tomchi tomiziladi.
   
3. 
   Hosil bo'lgan cho'kmalarning fizik xossalari o'rganiladi.
   

4. Bajarilgan tajribalar solishtirilgan holda xulosa chiqariladi va daftarda qayd etiladi.
Nazorat uchun savollar:

1. 
   Suvda erimaydigan asoslarga misollar keltiring.
   
2. 
   Suvda erimaydigan asoslarning parchalanishiga misollar keltiring.
   
3. 
   Suvda erimaydigan asoslarga indikator ta'sir etadimi?
