Ib yam li ntawd, koj tuaj yeem nug, puas yog Ca Oh 2 soluble lossis insoluble hauv dej?

Ca (OH )2 Nws tsuas yog me ntsis soluble hauv dej (0.16g Ca (OH )2/ 100g dej ntawm 20 ° C) tsim cov tshuaj hu ua txiv qaub dej. Lub solubility txo qis nrog nce kub. Kev ncua ntawm calcium hydroxide cov khoom hauv dej yog hu ua mis nyuj ntawm txiv qaub.

Tsis tas li ntawd, yog calcium hydroxide aqueous? Ca (OH) 2 yog ib yam khoom uas muaj me ntsis soluble hauv dej. Nws yog ib txwm hu ua slaked txiv qaub. Ntxiv dej ntau dhau rau me me ntawm Ca(OH)2 peb tuaj yeem tau txais ib qho dej Kev daws ntawm Ca (OH) 2 feem ntau hu ua dej txiv qaub.

Ntawm no, yuav ua li cas thaum calcium hydroxide tov nrog dej?

Calcium hydroxide , tseem hu ua slaked txiv qaub, Ca(OH)2, yog tau los ntawm qhov kev txiav txim ntawm dej ntawm calcium oxide. Thaum twg tov nrog dej , ib feem me me ntawm nws dissolves, tsim ib qho kev daws hu ua limewater, qhov seem seem li kev ncua hu ua mis nyuj ntawm txiv qaub.

Puas yog kev sib cais ntawm calcium hydroxide hauv dej endothermic lossis exothermic?

Cov solubility ntawm calcium hydroxide ntawm 70 ° C yog li ib nrab ntawm nws cov nqi ntawm 25 ° C. Yog vim li cas rau qhov tsis tshua muaj tshwm sim yog qhov dissolution ntawm calcium hydroxide hauv dej yog ib exothermic txheej txheem, thiab kuj ua raws li Le Chatelier txoj cai.
