Acids yog tshuaj tshuaj sib xyaw tias tso hydrogen ions (H +) thaum muab tso rau hauv dej. Piv txwv li, thaum hydrogen chloride tso rau hauv dej, nws tso nws hydrogen ions thiab cov daws ua hydrochloric acid. Bases yog chemical tshuaj sib xyaw uas attract hydrogen atoms thaum lawv muab tso rau hauv dej.
Xav txog qhov no, dab tsi yog qhov sib xyaw uas tsim cov hydrogen ions hauv kev daws teeb meem?
kua qaub. ib compound uas tsim hydrogen ions hauv cov kua , yog a hydrogen - ion pub, los yog ib qho khoom siv hluav taws xob-pair. acidic daws . ib yam daws hauv qhov twg hydrogen - ion concentration yog ntau dua li hydroxide- ion concentration.
Ib tug kuj yuav nug, vim li cas cov kev daws teeb meem yooj yim muaj H + ions? Qhov laj thawj yog tias dej ntawm nws tus kheej faib rau hauv hydrogen thiab hydroxide ions . Thaum a daws yog heev yooj yim , ntxiv hydroxide ions yuav hnov mob nrog txhua yam hydronium yuav luag sai li sai tau thaum nws tsim. Yog li cov concentration ntawm hydrogen ions yog tsawg heev, tsawg heev uas feem ntau yuav tsis quav ntsej.
Kuj tseem yuav paub yog, yog ib yam khoom uas tsim H + ions hauv cov dej?
Cov kua qaub
Puas yog nh3 tsim H + ions?
Nh3 yog tsis muaj zog puag ces nws attracts proton thiab h+ yog proton thiab nh3 ua muaj ib leeg ib leeg xwb nh3 ua teb nrog h+ thiab daim ntawv nh4+.. nws yog qauv yuav ua zoo li no..

Dab tsi yog cov txheej txheem uas nitrate ions thiab nitrite ions hloov mus rau nitrous oxide gas thiab nitrogen gas n2?
Nitrate ions thiab nitrite ions raug hloov mus rau nitrous oxide gas thiab nitrogen gas (N2). Cov cag ntoo nqus ammonium ions thiab nitrate ions siv los ua cov molecules xws li DNA, amino acids, thiab cov proteins. Organic nitrogen (cov nitrogen hauv DNA, amino acids, proteins) tawg mus rau ammonia, ces ammonium
Dab tsi yog qhov sib xyaw ua ke uas tsim cov hydrogen ions hauv kev daws teeb meem?
Kua qaub. compound uas tsim hydrogen ions hauv kev daws. puag. compound uas tsim hydroxide ions hauv kev daws. tsis pub
Puas yog cov kua qaub tsim hydronium ions thaum lawv yaj hauv dej?
Cov kua qaub yog ib qho sib xyaw uas yaj hauv dej los ua ib hom kev daws teeb meem. Chemically, cov kua qaub yog ib yam khoom uas tsim hydronium ions (H3O +) thaum yaj hauv dej. Thaum hydrochloric acid (HCl) yaj nyob rau hauv dej, nws ionizes, splitting mus rau hauv hydrogen (H +) thiab chlorine (Cl-) ions
Dab tsi yog qhov concentration ntawm hydronium ions nyob rau hauv ib qho kev daws teeb meem?
Cov dej ntshiab yog suav tias yog nruab nrab thiab qhov concentration ntawm hydronium ion yog 1.0 x 10-7 mol / L uas yog sib npaug rau hydroxide ion concentration
Dab tsi yog lub npe rau cov khoom uas yaj hauv dej tab sis tsis tsim ions lossis ua hluav taws xob tam sim no?
Ib qho electrolyte yog ib yam khoom uas tsim cov kua hluav taws xob thaum yaj hauv cov kuab tshuaj polar, xws li dej. Cov yaj electrolyte cais mus rau hauv cations thiab anions, uas disperse uniformly los ntawm cov kuab tshuaj. Hluav taws xob, xws li kev daws teeb meem yog nruab nrab
