Amaliy ish №1
Mavzu: „Galogenlar” mavzusiga oid tajribaviy masalalar yechish


Darsning maqsadi: Galogenlarni aniqlash, xossalarini bilish.
Kerakli jihozlar va reaktivlar:Pirabirkalar, pipetka, indikator qog’oz, quruq
yoqilg’i, qisqich, mis (II) oksidi, kumush nitrat, natriy iodid, rux bo’lakchalari, kalsiy oksidi.
Ishning borishi:
Ish quyidagi jadval asosida olib boriladi. Xlorid kislotasining asosiy xossalariga taaluqli o’tkaziladi. Tajribalar xavfsizlik qoidalariga rioya qilingan holda olib boriladi.

Kimyoviy birikma	Kuzatuv natijasi	Reaksiya tenglamasi
1. Xlorid kislotaning indikatorga ta’siri. A) lakmus qog’ozi B) metiloranj	A) Binafsha rangli lakmus qog’ozi qizil ranga kiradi. B) To’q sariq rangi qizil ranga kiradi
2. Xlorid kislotani metallar bilan ta’siri (Zn)	Gaz ajralishi bilan boradi	2HCl+Zn=ZnCl2 + H2
3. Xlorid ionini aniqlash uchun kumush nitrat eritmasidan foydalaniladi (sifat reaksiyasi	Xlorid kislotaga kumush nitrat qo’shilsa Oq cho’kma tushadi	HC1 +AgNO3=HNO3+ AgCl

Galogenlaming kumush bilan hosil qilgan birikmalarida cho’kma tushishi kuzatiladi.Sizga berilgan quruq tuz bariy xlorid ekanligini tajribalar yordamida isbotlang. Kerakli reaksiya tenglamalarini yozing.

Xulosa.
