Cov pH ntawm hydroiodic acid 1.85.
Ntxiv rau qhov no, pH ntawm hydrochloric acid yog dab tsi?
pH ntawm Common Acids thiab Bases
| Acid | Lub npe | 1 mM |
|---|---|---|
| H2SO4 | sulfuric acid | 2.75 |
| HI | hydroiodic acid | 3.01 |
| HBr | hydrobromic acid | 3.01 |
| HCl | hydrochloric acid | 3.01 |
Tsis tas li ntawd, pH ntawm carboxylic acid yog dab tsi? Cov pH ntawm carboxylic acid kev daws teeb meem Ethanoic kua qaub yog ib yam ntawm cov kua qaub qhov twg pawg -COOH txuas nrog ib pawg alkyl yooj yim. Cov kev daws teeb meem Typicallab muaj pH cov nyob rau hauv 2-3 ntau yam, nyob ntawm lawv cov concentrations.
Ntawm no, pH tus nqi ntawm sulfuric acid yog dab tsi?
Txij li thaum sulfuric acid yog ib tug muaj zog kua qaub , a 0.50 M daws sulfuric acid muaj ib pH nyob ze zero.
Qhov pH ntawm 12m HCl yog dab tsi?
Hauv kev xyaum, txhua cov kua qaub uas ua rau muaj qhov concentration ntawm hydrogen ions nrog lub molarity ntau dua 1 yuav raug xam kom muaj qhov tsis zoo. pH . Piv txwv li, lub pH ntawm 12M HCl ( hydrochloric acid) yog xam los yog -log(12) = -1.08.

Dab tsi yog hydroiodic acid siv rau?
Hydriodic Acid Siv & Ntau Feem ntau feem ntau siv los ua tus neeg sawv cev muaj zog vim tias nws txo qis peev xwm thiab acidity, lub hauv paus daim ntawv thov hydriodic acid yog siv rau kev tsim cov acetic acid. Txawm hais tias acetic acid yog tshuaj lom rau tib neeg hauv nws cov ntsiab lus, nws yog cov tshuaj siv los tsim cov kua txiv hmab txiv ntoo
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog cov khoom ntawm phosphorous acid Dab tsi yog nws cov mis?
Phosphorous acid (H3PO3) tsim cov ntsev hu ua phosphites, kuj siv los txo cov neeg ua haujlwm. Nws yog npaj los ntawm dissolving tetraphosphorus hexoxide (P4O6) los yog phosphorus trichloride (PCl3) hauv dej
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
