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.
Puas yog slaked txiv qaub acid los yog ntsev?
Teb: Cov txiv qaub ceev (calcium oxide) lossis cov txiv qaub slaked (calcium hydroxide) lossis chalk (calcium carbonate) yog base uas neutralizes acids.
Puas yog txiv qaub acidic lossis yooj yim?
CAUTION: Txiv qaub yog a lub hauv paus muaj zog thiab yuav tsim pH siab (alkaline) daws.
Puas yog cov tshuaj txiv qaub acidic?
txiv qaub (calcium oxide) yog cov khoom dawb uas muaj cov khoom siv zoo heev. Txiv qaub reacts nrog dej los tsim slaked txiv qaub, uas yog cov tshuaj lom neeg calcium hydroxide. … Calcium hydroxide yog soluble me ntsis hauv dej uas tsim cov tshuaj alkaline hu ua limewater.
Puas txiv qaub puas tsim kev puas tsuaj rau tib neeg?
Kev nqus cov hmoov av txiv qaub tuaj yeem ua rau khaus ua pa, hnoos thiab txham. Yog tias noj, txiv qaub tuaj yeem ua rau mob, ntuav, los ntshav, raws plab, poob ntshav siab, cev qhuav dej, thiab nyob rau lub sijhawm ntev, nws tuaj yeem ua rau cov hlab ntsha tawg lossis lub plab hauv ob sab phlu.
