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..
