Kauj ruam 3: Nws txhais tau tias Ag+ yog ua raws li kev cai lij choj kua qaub los ntawm kev lees txais khub ntawm electron los ntawm NH3 thiab NH3 yog ua raws li puag los ntawm pub ib khub ntawm electrons.
Ua raws li qhov no, puas yog CL lub hauv paus tsis muaj zog lossis pH nruab nrab?
NaClO yog weakly yooj yim vim ClO- yog qhov sib txuas puag ntawm a qaug zog acid , HClO (hypochlorous kua qaub ). Na+ forms a muaj zog - puag hydroxide, thiab yog li ntawd, nws tsis yog ib qho kua qaub . KCl yog pH - nruab nrab vim Cl - yog lub conjugate puag ntawm a muaj zog acid (thiab yog li no tsis yog ib puag ).
Tsis tas li, CN puas yog lub hauv paus tawv lossis mos? mos bases muaj cov loj, kuj polarizable pub atoms (xws li P, S, thiab Cl).
Nyuaj thiab Mos Acids thiab Bases.
| Cov kua qaub | Bases | |
|---|---|---|
| nyuaj | Ti4+ | PO43− |
| mos | BF3, Al2Cl6, CO2,SO3 | |
| Cu+, Ag+, Aw+, Tl+, Hg22+ | H− | |
| Pd2+, Pt2+, Hg2+ | CN−, SCN−, kuv−, RS− |
Ib sab saum toj no, puas yog CL acidic lossis yooj yim?
Nco ntsoov tias ntsev yuav tsuas yog qhov yooj yim yog tias nws muaj lub hauv paus conjugate ntawm cov kua qaub tsis muaj zog. Piv txwv li, sodium chloride muaj chloride (Cl–), uas yog lub hauv paus ntawm conjugate HCl . Tab sis vim HCl yog ib tug muaj zog acid, Cl– ion tsis yog qhov yooj yim hauv kev daws, thiab nws tsis muaj peev xwm deprotonating dej.
Puas yog NaOH acid lossis base?
NaOH yog a puag vim tias thaum yaj hauv dej nws dissociates rau Na + thiab OH- ions. Nws yog OH- (hydroxyl ion) uas ua rau NaOH ib puag . Nyob rau hauv classical lub sij hawm a puag yog txhais raws li ib tug compound uas reacts nrog ib kua qaub tsim ntsev thiab dej raws li tau piav qhia los ntawm kev sib npaug hauv qab no. NaOH + HCl = NaCl + H2O.

Puas yog ntsev daws acidic lossis yooj yim?
PH ntawm ntsev tov. Lub pH ntawm cov tshuaj ntsev yog txiav txim siab los ntawm tus txheeb ze lub zog ntawm nws ?conjugated acid-base khub. Cov ntsev tuaj yeem yog acidic, nruab nrab, lossis yooj yim. Cov ntsev uas tsim los ntawm cov kua qaub uas muaj zog thiab lub hauv paus tsis muaj zog yog cov ntsev ntsev, xws li ammonium chloride (NH4Cl)
Puas yog activated charcoal acidic lossis alkaline?
Tau ntau xyoo, activated charcoal tau siv rau kev kho mob thaum muaj xwm txheej ceev ntawm qee yam tshuaj lom. Nws cov khoom alkaline tso cai rau nws khi rau cov tshuaj lom thiab tiv thaiv lawv los ntawm kev nqus ntawm lub plab mus rau hauv cov hnyuv
Puas yog chlorine yooj yim lossis acidic?
Chlorine gas bleached daim ntawv litmus. Qhov no yog vim muaj cov hypochlorite ions. Yog li, thaum chlorine (txhua daim ntawv) ntxiv rau hauv dej, cov kua qaub tsis muaj zog hu ua Hypochlorousacid yog tsim. Nws yog cov kua qaub no, tsis yog cov tshuaj chlorine, uas muab dej nws lub peev xwm los oxidize thiab tua kab mob
Yuav ua li cas koj txiav txim siab yog hais tias ib yam khoom yog acidic los yog yooj yim?
Txhawm rau txiav txim siab seb cov khoom puas yog acid orabase, suav cov hydrogens ntawm txhua yam khoom ua ntej thiab tom qab cov tshuaj tiv thaiv. Yog hais tias tus naj npawb ntawm hydrogenshas txo cov tshuaj yog cov kua qaub (donates hydrogen ions). Yog tias tus naj npawb ntawm hydrogens tau nce ntxiv tias cov khoom yog lub hauv paus ( lees txais hydrogenions )
Puas yog cov lus ntsev acidic lossis yooj yim?
Properties of Table Salt: Rooj ntsev yog cov khoom tsim los ntawm neutralization ntawm cov kua qaub los ntawm lub hauv paus. Yog li nws tsis yog Acid lossis Base. Koj tuaj yeem siv pH Scale los qhia seb nws cov kua qaub lossis lub hauv paus
