Calcium cyanide decomposes rau tsis tshua muaj tshuaj lom thiab flammable hydrogen cyanide thiab tshuaj lom thiab irritating nitrogen oxides thaum rhuab hauv hluav taws.
QHOV 9. Lub cev thiab tshuaj lom neeg.
| Lub cev lub cev: | Khoom |
|---|---|
| Basicity: | Reacts maj mam nrog dej los tsim calcium hydroxide, uas yog lub hauv paus muaj zog. |
Kuj paub yog, yog cyanide acidic los yog yooj yim?
Hydrogen cyanide yog qaug zog acidic nrog pkib ua 9.2. Nws ib nrab ionizes nyob rau hauv dej tov muab cov cyanide ib, CN−. Ib qho kev daws ntawm hydrogen cyanide Hauv dej, sawv cev ua HCN, hu ua hydrocyanic kua qaub . Cov ntsev ntawm cov cyanide anion yog hu ua cyanide.
Ib yam li ntawd, cyanide cuam tshuam li cas pH? Cyanide yuav nyiam tshaj tawm cov zaub mov sulfide thiab yuav hnov mob nrog sulfur los tsim thiocyanate. Cov tshuaj tiv thaiv no tseem yuav txhim kho cov oxidation ntawm cov kab mob uas txo cov sulfur, ua kom cov kev xav tau ntawm cov txiv qaub ntxiv los tswj cov pH nyob rau theem txaus kom tsis txhob volatilization ntawm hydrogen cyanide (HCN).
Cov lus nug tseem yog, cov mis calcium cyanide yog dab tsi?
Ca(CN) 2
Puas yog cyanide ib qho organic compound?
A compound yog organic yog tias nws muaj cov pa roj carbon. Hydrogen Cyanide , los yog HCN, muaj Hydrogen, Carbon, thiab Nitrogen. Vim nws muaj carbon, nws yog organic . Keeb kwm, qee qhov cyanide tau raug suav hais tias inorganic.

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Puas yog urea yog cov kua qaub lossis lub hauv paus?
Dissolved hauv dej, nws tsis yog acidic noralkaline. Lub cev siv nws nyob rau hauv ntau cov txheej txheem, tshwj xeeb tshaj yog nitrogen excretion. Lub siab tsim nws los ntawm kev sib txuas ob ammoniamolecules (NH3) nrog carbon dioxide (CO2) molecule nyob rau hauv lub voj voog urea
Puas yog sodium hydrosulfide yog cov kua qaub lossis lub hauv paus?
Ib tug chemical puag. Reacts nrog cov kua qaub kom tso cov nplaim hluav taws thiab cov pa phem gaseous hydrogen sulfide. Tsuav yog cov tshuaj khaws cia muaj zog alkaline, pH> 10, muaj tsawg heev tso H2S. Ntawm pH = 7, qhov feem pua ntawm H2S tso tawm yog ze rau 80%
Puas yog Hydronium yog cov kua qaub lossis lub hauv paus?
Hauv cov tshuaj acidic, hydronium yog qhov ua haujlwm ntau dua, nws cov proton ntau dhau tau yooj yim rau cov tshuaj tiv thaiv nrog hom kab mob. Hydronium ion yog acidic heev: ntawm 25 ° C, nws pKa yog kwv yees li 0
Cov tshuaj ntxuav qhov cub puas yog cov kua qaub lossis cov hauv paus?
Ntau yam khoom siv tu, xws li xab npum thiab qhov cub ntxuav, yog cov hauv paus. Bases neutralize (tso tawm) acids. Alkalis yog cov hauv paus uas yaj hauv dej. Qhov ntau hydroxide ions ib lub hauv paus muaj, nws muaj zog dua
