Kev tshwm sim ntawm Puag nrog Hlau :
Thaum alkali ( puag ) reacts nrog hlau , nws tsim ntsev thiab hydrogen gas. Piv txwv li: Sodiumhydroxide muab hydrogen gas thiab sodium zincate thaum reacts nrog zinc hlau . Sodium aluminate thiab hydrogen gas yog tsim thaum sodium hydroxide reacts nrog aluminium hlau.
Ntawm no, yuav ua li cas tshwm sim thaum acid thiab base react nrog hlau?
Acids thiab Bases React nrog Hlau Bases React nrog qhov tseeb hlau xws li zincor aluminium piv txwv los kuj tsim cov roj hydrogen. Sodiumhydroxide reacts nrog zinc thiab dej los tsim sodium zincate thiab hydrogen gas.
Cov hlau uas ua rau lub hauv paus hu ua dab tsi? Piav: Feem ntau hlau yuav tsis react withbases . Tab sis lwm tus, hu ua amphoteric hlau , tej zaum yuav ntsev nrog lawv.
Tom qab ntawd, ib tug kuj yuav nug, yuav ua li cas tshwm sim thaum hlau oxide reacts nrog puag?
Cov tshuaj tiv thaiv hlau Oxide Cov oxides ntawm hlau yog qhov yooj yim. Yog ib hlau oxide dissolves nyob rau hauv dej, nws yuav tsim ib hlau hydroxide. Zoo li ib yam puag , cov hauv paus tuaj yeem beneutralized los ntawm cov kua qaub los tsim cov ntsev thiab dej. Feem ntau, cov cim xim hlau ib lub caij muaj, qhov yooj yim dua nws oxide yuav yog.
Vim li cas cov hauv paus tsis hnov mob nrog hlau?
Zinc hlau kuj teb nrog sodiumhydroxide tov los tsim hydrogen gas. Tag nrho cov hlau tsis cuam tshuam nrog hauv paus tsim ntsev thiab hydrogen. Somenon- hlau react nrog hauv paus tab sis tsis muaj hydrogengas yog tsim. Ib txhia hlau yog chemically heev reactive whereas lwm yam hlau tsawg reactive los yog unreactive.

Yuav ua li cas thaum barium chloride reacts nrog poov tshuaj sulfate?
Thaum barium chloride reacts nrog potassium sulfate, barium sulfate thiab potassium chloride arc tsim. Qhov sib npaug sib npaug rau cov tshuaj tiv thaiv no yog: BaCl_2(aq) + K_2SO_4(aq) rightarrow BaSO_4(s) + 2KCl(aq) Yog tias 2 moles ntawm poov tshuaj sulfate react, Cov tshuaj tiv thaiv noj moles ntawm barium chloride
Yuav ua li cas tshwm sim thaum bromine reacts nrog ib tug alkene?
Alkenes hnov mob hauv qhov txias nrog cov kua ntshiab bromine, lossis nrog kev daws ntawm bromine hauv cov kuab tshuaj organic xws li tetrachloromethane. Qhov ob daim ntawv cog lus tawg, thiab ib qho bromine atom ua txuas rau txhua cov pa roj carbon. Cov bromine poob nws cov xim liab-xim av kom muab cov kua tsis muaj xim
Yuav ua li cas tshwm sim thaum sodium reacts nrog hydrochloric acid?
Sodium hlau reacts nrog hydrochloric acid los ua ntsev thiab hydrogen gas. Qhov no txhais tau hais tias koj cov reactants yuav yog sodium hlau thiab hydrochloric acid, vim cov no yog cov khoom uas tau hloov mus rau hauv cov ntsev thiab hydrogen gas
Yuav ua li cas thaum hlau sulfide reacts nrog sulfuric acid?
Thaum cov hlau sulfide ntxiv rau dilute sulfuric acid, koj yuav tau txais hlau sulfate, dej thiab sulfur dioxide raws li cov khoom
