Hom 2: thaum a muaj zog acid / puag reacts nrog a tsis muaj zog puag / kua qaub Yog hais tias hydronium thiab hydroxyl ions muaj nyob rau hauv qhov sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog raug tso tawm uas tsawg dua 57 kj / mole vim yog dissociation ntawm lub qaug zog acid / puag uas feem ntau yog endothermic.
Tsuas yog li ntawd, yuav ua li cas thaum muaj zog acid reacts nrog lub hauv paus tsis muaj zog?
Titration ib tsis muaj zog puag nrog a muaj zog acid . Hauv ib tsis muaj zog puag - muaj zog acid titration, ua kua qaub thiab puag yuav teb tsim ib acidic daws. Ib conjugate kua qaub yuav raug tsim thaum lub sij hawm titration, uas ces reacts nrog dej los tsim hydronium ions. Qhov no ua rau muaj kev daws teeb meem nrog pH qis dua 7.
Ib tug kuj yuav nug, yuav ua li cas tshwm sim thaum koj sib tov cov kua qaub thiab lub hauv paus ntawm sib npaug zog? Arrhenius Cov kua qaub thiab Bases Ua ke rau daim ntawv ntsev thaum koj muab ib tug Arrhenius kua qaub thiab puag Nyob rau hauv tib txoj kev daws teeb meem, qhov zoo them hydronium ions ua ke nrog cov hydroxide ions los tsim cov dej, thiab cov ions seem ua ke los tsim cov ntsev. Lawv muab tso rau hauv daim ntawv NaCl, los yog cov lus ntsev.
Tsuas yog li ntawd, yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug qaug zog acid?
Yog ib muaj zog acid yog ntxiv rau qhov tsis, qhov qaug zog puag yuav teb nrog H+ los ntawm muaj zog acid tsim lub qaug zog acid HA: H+ + A- → HA. Tus H+ tau absorbed los ntawm A- es tsis txhob reacting nrog dej los ua H3O+ (H+), yog li pH hloov me ntsis.
Lub hauv paus tsis muaj zog tuaj yeem ua rau muaj zog acid?
Muaj zog acids yuav neutralize lub hauv paus muaj zog ntawm qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug. Ntau qhov ntim ntawm a qaug zog acid yog xav tau neutralize lub hauv paus muaj zog yog tias cov concentrations sib npaug thiab sib piv rau tsis muaj zog hauv paus thiab muaj zog acids . Ib qho tsis yog ib qho kev daws teeb meem uas muaj a qaug zog acid thiab ntsev nrog tib lub anion li tus kua qaub.

Yuav ua li cas tshwm sim thaum ib tug muaj zog acid yaj nyob rau hauv dej?
Thaum cov kua qaub yaj hauv dej, ib qho proton (hydrogen ion) raug xa mus rau cov dej molecule los tsim cov hydroxonium ion thiab qhov tsis zoo ion nyob ntawm seb cov kua qaub koj pib li cas. Cov kua qaub muaj zog yog ib qho uas yuav luag 100% ionised hauv kev daws. Lwm cov tshuaj muaj zog muaj xws li sulfuric acid thiab nitric acid
Yuav ua li cas tshwm sim thaum aqueous tov ntawm sodium sulphate thiab barium chloride sib tov?
Thaum cov tshuaj aqueous ntawm sodium sulphate reacts nrog ib tug aqueous tov ntawm barium chloride, precipitate ntawm barium sulphate yog tsim thiab tom qab cov tshuaj tiv thaiv tshwm sim. ii. Yog hais tias cov reactants nyob rau hauv lub cev muaj zog, ces cov tshuaj tiv thaiv yuav tsis tshwm sim. Nws yog ib qho kev hloov pauv ob npaug nrog rau nag lossis daus
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas tshwm sim thaum koj ntxiv ib tug qaug zog acid rau dej?
Thaum cov kua qaub uas tsis muaj zog ntxiv rau hauv dej, cov ntaub ntawv sib npaug sib npaug hauv cov kua qaub molecules, HA (aq), hnov mob nrog cov dej ua kua los tsim cov aqueous hydronium ions thiab aqueous anions, A-(aq). Cov tom kawg yog tsim thaum cov kua qaub molecules poob H + ions rau dej
Yuav ua li cas tshwm sim yog tias koj tov cov kua qaub uas muaj zog sib npaug?
Yuav ua li cas tshwm sim yog tias koj tov cov kua qaub uas muaj zog sib npaug? Koj yuav pom cov tshuaj tiv thaiv tawg. Cov kua qaub yuav rhuav tshem lub hauv paus. Lub hauv paus yuav rhuav tshem cov kua qaub
