A hydronium ion yog sau li H3O+. Nws yog tsim Thaum lwm yam pub dawb proton, lossis H +, rau cov dej molecule. H + yuav yooj yim khi rau ib qho ntawm ob leeg ib leeg ntawm electrons nyob ib ncig ntawm cov dej molecule. Lub atom hydrogen tsuas muaj ib tug proton thiab ib tug electron.
Hauv qhov no, vim li cas hydronium ion zoo?
Tag nrho cov electrons = 10, tag nrho cov protons = 10, tag nrho tsis muaj nqi. Ib hydrogen ion yog qhov zoo vim nws muaj ib tug proton thiab tsis muaj electrons. Koj ntxiv ib hydrogen ion mus rau dej thiab koj tau txais ib hom uas tag nrho muaj ib tug ntau proton tshaj electron. Nws yog li ntawd zoo raug nqi.
Tsis tas li ntawd, tus nqi ntawm hydronium ion yog dab tsi? Cov hydronium ion muaj ib nqi ntawm +1. Nws muaj cov tshuaj formula H3 O +. Hydronium ions yog tsim thaum lub acid reacts nrog dej.
Kuj paub, koj yuav nrhiav tau cov hydronium ion li cas?
Koj ua tau xam qhov concentration ntawm hydronium ions hauv kev daws yog tias koj paub qhov concentration ntawm hydroxide ions los ntawm kev siv lub qauv [OH-] x [H3O+] = 10-14. Koj tuaj yeem ua tau xam qhov concentration ntawm hydronium ions Yog hais tias lub pH, los yog tsis zoo cav ntawm cov concentration ntawm H30 +, yog paub los ntawm kev siv cov qauv [H3O+] = 10-pH.
Hydronium yog siv rau dab tsi?
Qhov chaw ntawm Hydronium Qhov sib piv ntawm hydroxide thiab hydronium ions tuaj yeem yog siv rau xam cov tshuaj pH. Cov hom no tshwm sim thaum twg Arrhenius acid yaj hauv dej. Hydronium muaj nyob rau hauv cov huab interstellar thiab nyob rau hauv lub tails ntawm comets.

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Yuav ua li cas compound yuav tsim yog Aluminium thiab oxygen tau ua ke?
Aluminium tuaj yeem hnov mob nrog cov pa oxygen los tsim cov txhuas oxide (Al_2O_3)
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
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
Yuav ua li cas yuav tsum tshwm sim rau electrons los tsim spectral kab?
Thaum cov electrons txav los ntawm qib siab zog mus rau qis dua, photons raug tso tawm, thiab cov kab hluav taws xob tuaj yeem pom hauv spectrum. Cov kab nqus tau pom thaum electrons nqus photons thiab txav mus rau qib siab zog. Yog hais tias lub atom tau poob ib los yog ntau dua electrons, nws yog hu ua ion thiab hais tias yuav ionized
