Synthesis txoj kev ntawmCobalt (II) hydroxide:

1. Cov qauv hluav taws xob hluavtaws: Cobalt uas muaj cov khib nyiab ntau ntau ntau cov khoom pov tseg tau yaj los ntawm nitric acid thiab hydrochloric acid. Cov tau cobalt cobalide tov yog huv nrog hydrogen peroxide kom tshem tawm cov hlau. Yog tias tsim nyog, sodium carbonate lossis ammonia dej ntxiv rau kom paub tseeb tias ua tiav kev ua kom huv. Lub lim dej cobalt chloride tov yog ntxiv rau sodium hydroxide los tsim cobalt hydroxide, uas yog tom qab ntawd ntxuav thiab centrifuged los tsim cov cobalt hydroxide cov khoom.

2. Electrolysis txoj kev: nws tau los ntawm electrolysis ntawm ntsev tov nrog cobalt ua anode.

3. Lub sulfate lossis nitrate ntawm cov kev cob qhia kev cob qhia nrog alkali los tsim cob lub zog hydroxide. Dissolve 100g Coso₄ · 7H₂O Hauv dej los ua kev daws teeb meem ze li ntawm kev daws teeb meem. Ntxiv 42g sodium hydroxide hauv 60ml dej los ua cov alkali kev daws teeb meem hauv qab cov cua sov thiab txuas ntxiv nplawm. Cov kev txiav txim siab nag lossis daus yog nqa tawm hauv lub beaker ntev, uas yog qhov ua kom pom tseeb rau kev sib tov ntawm cov sib tov. Cov nag los nag ua tsim tau thaum pib xiav. Thaum nws yog rhuab rau ntawm cov dej da dej, cov nag lossis nag ceev hloov liab. Tom qab hais meej, decant thiab ntxuav nrog dej rau ob peb zaug, tom qab ntawd lim ntawm buchner funnel thiab ntxuav nrog dej kom txog thaum lub tshuab ntxhua khaub ncaws. Thaum kawg, nws tau qhuav hauv lub tshuab nqus tsev nruab nrog fultrated h₂Yog li₄Cov. Txij li thaum cobalt hydroxide yuav tau maj mam oxidized nyob rau hauv huab cua, kev npaj ua haujlwm yog qhov zoo tshaj plaws tau nqa tawm hauv lub thawv ua haujlwm tiv thaiv los ntawm kev ua haujlwm roj.

4. Siv hlau cobalt kom hnov ​​mob nrog dilute nitric acid ntawm qhov kub ntawm 60 ~ 70 degree. Thaum cov tshuaj tiv thaiv nres, ntxiv cov dej poob, cais cov hlau tshaj li, ntxiv coco₃Txhawm rau kom daws rau nruab nrab, thiab khaws nws ntawm qhov kub no rau 2 ~ 3h, lim thiab tshem tawm cov teeb meem insoluble. Tom qab ntawd maj mam ntxiv 2% ammonia nyob rau hauv nruam nplawm thiab cua sov, yog li ntawd rau hauv lub teeb liab nag ceev. Tom qab cov tshuaj tiv thaiv tau ua tiav thiab meej, nqus tawm cov tshuaj nrog cov dej, thiab qhuav nws hauv lub tshuab nqus tsev muaj cov tshuab nqus tsev zoo nkauj nrog H₂Yog li_4.
