Thaum twg tsis tau them nqi qaug zog acid yog ntxiv rau dej , homogeneous equilibrium cov ntaub ntawv uas aqueous kua qaub molecules, HA(aq), react nrog kua dej tsim aqueous hydronium ions thiab aqueous anions, A-(aq). Cov tom kawg yog tsim thaum lub kua qaub molecules poob H+ ions rau dej.
Kuj nug, ua li cas thaum koj muab cov kua qaub tsis muaj zog hauv dej?
A qaug zog acid yog ib qho uas tsis ionise tag nrho thaum nws yog yaj nyob rau hauv dej . Ethanoic kua qaub yog ib yam qaug zog acid . Nws reacts nrog dej los tsim hydroxonium ions thiab ethanoate ions, tab sis cov tshuaj tiv thaiv rov qab muaj kev vam meej dua li yav tom ntej. Cov ions hnov mob yooj yim heev los hloov kho kua qaub thiab cov dej.
Qhov thib ob, yuav ua li cas thaum lub zog tsis muaj zog yog diluted? Tej yam tseem ceeb uas yuav tsum nco ntsoov thaum peb dilute ib tug aqueous tov ntawm a qaug zog acid ntawm 25 ° C thiab 1 atm yog tom qab dilution cov resultant tov muaj: ib tug qis concentration ntawm kua qaub . qis concentration ntawm hydrogen ions. pH siab dua.
Tsis tas li ntawd, yuav ua li cas yog tias koj ntxiv dej rau acid?
Cov cua kub ntau yog tso tawm thaum muaj zog kua qaub yog tov nrog dej . Ntxiv ntau kua qaub tso cua sov ntau. Yog tias koj ntxiv dej rau acid , koj tsim ib tug heev concentrated tov ntawm kua qaub pib. Thaum tshav kub kub tso tawm ntau npaum li cas cov tshuaj yuav boil heev hnyav, splashing concentrated kua qaub tawm ntawm lub thawv!
Puas yog pH hloov thaum koj ntxiv dej?
Ntxiv dej mus rau ib tug acid los yog puag yuav hloov nws pH . Dej yog feem ntau dej molecules yog li ntawd ntxiv dej mus rau ib qho kua qaub los yog hauv paus txo cov concentration ntawm ions hauv cov tshuaj. Thaum ib tug acidic tov yog diluted nrog dej qhov concentration ntawm H + ions txo thiab cov pH ntawm kev daws nce mus rau 7.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
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 koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Yuav ua li cas tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
Yuav ua li cas tshwm sim thaum dilute sulfuric acid ntxiv rau hlau sulfide?
A. Thaum twg ?dilute sulfuric acid ntxiv rau kev sib xyaw ntawm cov hlau txhaws thiab cov hmoov sulfur, cov tshuaj tiv thaiv occusrs ntawm dilute sulfuric acid thiab hlau filings uas tsim ferrous sulphate thiab evolution ntawm hydrogen. FeS tsim reacts nrog sulfuric acid los tsim ferrous sulphate thiab tso tawm hydrogendisulphide gas
