Neutralization yog ib hom tshuaj tiv thaiv uas muaj zog kua qaub thiab lub hauv paus muaj zog react nrog ib leeg los tsim dej thiab ntsev.
Tsis tas li ntawd, cov tshuaj tiv thaiv zoo li cas yog cov tshuaj tiv thaiv neutralization?
Cov tshuaj tiv thaiv neutralization yog thaum ib qho kua qaub thiab lub hauv paus react tsim dej thiab ntsev thiab koom nrog ua ke ntawm H+ ions thiab OH- ions los tsim dej. Lub neutralization ntawm lub zog kua qaub thiab lub hauv paus muaj zog muaj pH sib npaug rau 7.
neutralization cov tshuaj tiv thaiv yog dab tsi muab 2 piv txwv? Piv txwv - 1: Thaum Sodium hydroxide ntxiv rau hydrochloric kua qaub . Sodium chloride thiab dej yog tsim. Piv txwv - 2: Mis ntawm magnesia, uas yog lub hauv paus, yog muab raws li antacid nyob rau hauv cov ntaub ntawv ntawm indigestion, kom neutralize ntau kua qaub ua rau hauv plab.
Ib yam li ntawd, nws raug nug, dab tsi yog qhov tsis zoo ntawm cov tshuaj tiv thaiv hauv chemistry?
Hauv chemistry , neutralization los yog neutralization (saib qhov sib txawv ntawm kev sau ntawv) yog a tshuaj tiv thaiv nyob rau hauv uas ib tug acid thiab ib tug puag teb quantitatively nrog ib leeg. Hauv ib tshuaj tiv thaiv hauv dej, neutralization ua rau tsis muaj ntau tshaj ntawm hydrogen lossis hydroxide ions tam sim no hauv cov tshuaj.
Koj ua li cas neutralization cov tshuaj tiv thaiv?
Neutralization Reactions
- acid + puag → dej + ntsev.
- HCl(aq) + KOH(aq) → H 2O(ℓ) + KCl(aq)
- 2 HCl(aq) + Mg(OH) 2(aq) → 2 H 2O(ℓ) + MgCl 2(aq)
- 3 HCl(aq) + Fe(OH) 3(s) → 3 H 2O(ℓ) + FeCl 3(aq)
- HCl(aq) + NaOH(aq) → H 2O(ℓ) + NaCl(aq)
- H +(aq) + Cl −(aq) + Na +(aq) + OH −(aq) → H 2O(ℓ) + Na +(aq) + Cl −(aq)
- H +(aq) + OH −(aq) → H 2O (ℓ)
Pom zoo:
Cov tshuaj twg yog ib txwm tsim los ntawm cov tshuaj tiv thaiv neutralization?
Cov tshuaj tiv thaiv acid-base neutralization ib txwm ua rau ntsev. Qee zaum dej tsuas yog tsim cov tshuaj tiv thaiv uas muaj cov ntses bass thaj tsam muaj zog. Yog li cov lus teb yog ntsev
Dab tsi yog qhov tseeb ntawm cov ntsev tsim nyob rau hauv cov tshuaj tiv thaiv neutralization ntawm hydrochloric acid nrog barium hydroxide?
Lus Nug: Dab tsi yog cov qauv ntawm cov ntsev tsim nyob rau hauv Neutralization Reaction ntawm Hydrochloric Acid Nrog Barium Hydroxide? BaCl BaCl2 BaClH BaH2 BaO
Dab tsi yog qhov sib npaug ntawm cov tshuaj tiv thaiv neutralization?
Reactions of Acids and Bases A ntsev yog ib qho nruab nrab ionic compound. Cia peb saib yuav ua li cas cov tshuaj tiv thaiv neutralization ua rau dej thiab ntsev, siv ua piv txwv cov tshuaj tiv thaiv ntawm kev daws teeb meem ntawm hydrochloric acid thiab sodium hydroxide. Tag nrho qhov sib npaug ntawm cov tshuaj tiv thaiv no yog: NaOH + HCl → H2O thiab NaCl
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
Dab tsi yog cov reactants ntawm cov tshuaj tiv thaiv neutralization?
Neutralization tshwm sim thaum ob lub reactants, ib qho kua qaub thiab lub hauv paus, ua ke los tsim cov khoom ntsev thiab dej
