Calcium hydroxide , tseem hu ua slaked txiv qaub, Ca(OH)2, yog tau los ntawm kev ua dej ntawm calcium oxide.
Slaked txiv qaub siv rau hauv chemistry yog dab tsi?
Rau manufacturing of sugar - Slaked txiv qaub yog siv rau kev tsim cov suab thaj los ntawm cane. Nws ua rau qab zib kua txiv alkaline thiab precipitates nws impurities. Nws yog siv hauv kev kho dej phwj tuaj. Nws yog siv los ua flocculant hauv dej.
Thaum slaked txiv qaub raug tsim?
Tsis tas li, los ntawm saum toj no nws tau pom tseeb tias calcium oxide thiab dej hnov qab ua 'calcium hydroxide lossis slaked txiv qaub'. Thaum dhau ntawm CO2 dhau los ntawm cov tshuaj tiv thaiv saum toj no, cov mis nyuj ploj vim yog tsim cov calcium bicarbonate soluble. Cov tshuaj tiv thaiv yog: CaCO3 + CO2 + H2O → Ca (HCO3) 2 (Soluble).
Puas hydrated txiv qaub yog tshuaj?
Hydrated txiv qaub, tseem hu ua calcium hydroxide thiab ib txwm hu ua slaked txiv qaub yog an inorganic compound Nws cov mis molecular yog Ca(OH) 2CAS: 1305-62-0. Tsis muaj kev tiv thaiv raug rau cov ntshiab ntshiab concentration ntawm hydrated txiv qaub tuaj yeem ua rau mob hnyav heev.
Puas hydrated txiv qaub noj tsis zoo?
Khoom noj khoom haus qib calcium hydroxide feem ntau muaj kev nyab xeeb. Txawm li cas los xij, yog tias koj ua haujlwm nrog qib qib calcium hydroxide, noj nws tuaj yeem ua rau calcium hydroxide lom. Qhov no tuaj yeem ua rau raug mob hnyav lossis tuag.

Puas yog slaked txiv qaub acidic lossis yooj yim?
Nws solubility txo qis nrog qhov kub thiab txias. Nws suspension nyob rau hauv dej yog hu ua mis nyuj ntawm txiv qaub. Nws yog insoluble hauv cawv. Nws yog basic lossis alkaline yog xwm . Puas yog slaked txiv qaub a base? Puas yog calcium hydroxide acidic lossis yooj yim?
Puas slaked txiv qaub acidic?
Kuj feem ntau hu ua slaked txiv qaub los yog txiv qaub hydrated; calcium hydroxide yog tsim los ntawm hydrating txiv qaub (calcium oxide, CaO). Txiv qaub yog nyob deb ntawm kev lag luam zoo tshaj plaws alkaline reagent siv rau acid neutralization.
Thaum twg slaked txiv qaub siv?
Rau kev tsim cov suab thaj - Slaked txiv qaub yog siv rau hauv kev tsim cov suab thaj los ntawm cov cane. Nws ua rau qab zib kua txiv alkaline thiab precipitates nws impurities. Nws yog siv hauv kev kho dej phwj. Nws yog siv los ua flocculant hauv dej .
