Ntuj nag:
" Ib txwm " nag los me ntsis acidic vim muaj cov carbonic yaj kua qaub . Cov pa roj carbon kua qaub yog tib yam li uas pom nyob rau hauv dej qab zib pop. pH ntawm " ib txwm " nag tau ib txwm muab tus nqi ntawm 5.6.
Kuj tseem paub yog, yog cov dej nag ib txwm acidic lossis yooj yim?
Cov dej ntshiab yog nruab nrab nrog Ph ntawm 7. Dej nag , txawm li cas los xij muaj ib qho nruab nrab Ph ntawm txog 5.6 nrog me ntsis txawv nyob ntawm qhov chaw. Qhov no txhais tau tias dej nag yog me ntsis acidic , tab sis feem ntau tsis yog acidic txaus ua phem.
Qhov thib ob, qhov pH ntawm cov dej nag yog dab tsi? 5.6 rau 5.8
Tsis tas li ntawd, cov dej nag puas acidic?
Qhov ntsuas yog li ntawm xoom mus rau 14, nrog ntshiab dej nyob nruab nrab 7.0. Feem ntau dej Txawm li cas los xij, tsis yog qhov tseeb. Txawm huv, ib txwm nag muaj ib pH ib kb5.6. Qhov no yog vim nws reacts nrog carbon dioxide nyob rau hauv cov huab cua thiab tsim me me acidic carbonic kua qaub ua ntej nws yuav nag.
Dab tsi tuaj yeem ua rau dej nag acidic?
Acid los nag yog tshwm sim los ntawm cov tshuaj tiv thaiv uas pib thaum cov tebchaw xws li sulfur dioxide thiab nitrogen oxides raug tso tawm rau saum huab cua. Cov tshuaj no ua tau nce siab heev rau hauv cov huab cua, qhov chaw uas lawv sib tov thiab hnov mob nrog dej, oxygen, thiab lwm yam tshuaj los tsim ntau dua acidic pollutants, hu ua kua qaub nag.

Cov kua dej thiab hom kua dej yog dab tsi?
Cov kua dej tuaj yeem muab faib ua plaub yam yooj yim. Cov kua dej zoo tagnrho. Cov kua dej tiag tiag. Newtonian kua dej. Tsis yog-Newtonian Fluid
Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Puas muaj zog npaum li cas yog cov kua qaub los yog cov hauv paus daws teeb meem?
Qhov ntau ntawm 0 mus rau 14 muab kev ntsuas ntawm kev sib piv lub zog ntawm cov kua qaub thiab cov hauv paus daws teeb meem. Cov dej ntshiab thiab lwm cov kev daws teeb meem nruab nrab muaj tus nqi pH ntawm 7. Tus nqi pH tsawg dua 7 qhia tias cov kua qaub yog acidic, thiab pH tus nqi ntau dua 7 qhia tias cov tshuaj yog qhov yooj yim
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 tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
