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? Calcium hydroxide, tseem hu ua slaked txiv qaub (nrog rau cov tshuaj formula Ca (OH) 2) yog ib qhov chaw ntawm hydroxide ions thaum yaj nyob rau hauv aqueous daws. Yog li no, compound is a base.
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 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.
Vim li cas thiaj hu ua txiv qaub?
Calcium hydroxide, tseem hu ua slaked txiv qaub, Ca(OH)2, yog tau txais los ntawm kev ua dej ntawm calcium oxideThaum sib tov nrog dej, ib feem me me ntawm nws dissolves, tsim ib qho kev daws hu ua limewater, qhov seem seem yog ncua kev kawm hu ua mis nyuj ntawm txiv qaub.
