II variant
Tajriba: Mis(II) gidroksidini hosil qilish.
Mis (II) oksidini kukunidan tarozida 1 gtortib probirkaga soling, ustiga mol miqdoriga xlorid kislota eritmasidan quying. Spitr lampasi yoki quruq spirt yordamida mis (II) oksid eri ketguncha qizdiring. So’ngra hosil bo’lgan rangli eritma ustiga ishqor eritmasidan quying, ajralib chiqqan cho’kmani filtirlab, chinni kosachaga solib va ozgina quriting, so’ngra tarozida tortib o’lchanng.
O’tkazgan Tajribangizni reaksiya tenglamalarini yozing va hosil bo’lishi keak bo’lgan Cu(OH)₂ ni hisoblang hamda siz hosil qilgan mis (II)- gidroksidning massasi bilan taqqoslang.
