Nws tsim cov hmoov dawb, muaj xim tsis muaj xim, tsis muaj xim, thiab cov khoom ionic uas yog monopotassium ntsev ntawm phthalic acid. KHP yog me ntsis acidic, thiab nws yog feem ntau siv los ua ib tug thawj tus qauv rau acid-base titrations vim nws yog khoom thiab huab cua-ruaj khov, ua kom yooj yim rau hnyav kom raug. Nws tsis yog hygroscopic.
Tsis tas li, vim li cas NaOH tsis siv los ua tus qauv tseem ceeb?
a) nqus dej noo los ntawm huab cua. N os H NaOH NaOH yog tsis yog haum rau siv raws li ib tug thawj tus qauv vim tias lawv tau yooj yim nqus dej, H 2 O H_2O H2O, los ntawm huab cua. Lawv yooj yim nqus carbon dioxide los ntawm cov cua.
Ib yam li ntawd, qhov sib npaug ntawm cov poov tshuaj hydrogen phthalate yog dab tsi? Potassium Hydrogen Phthalate
| Potassium Hydrogen Phthalate Potassium Acid Phthalate, KHP | |
|---|---|
| Tshuaj Formula | HOCO (C6H4) COJ |
| Formula hnyav | 204.22 |
| Qhov hnyav sib npaug | 204.22 (Molar = Li qub) |
| CAS Nr. | 877-24-7 |
Ib yam li ntawd, lub hom phiaj ntawm kev siv potassium hydrogen phthalate hauv qhov kev sim no yog dab tsi?
Nws yog siv los txiav txim siab qhov concentration ntawm lub hauv paus. Peb paub cov molar loj ntawm cov qauv thiab kuj qhov hnyav ntawm KHP.
Puas yog HCl yog thawj tus qauv?
Hydrochloric acid , HCl thiab sulfuric acid, H2YOG4, tsis haum rau siv raws li ib tug thawj tus qauv vim hais tias txawm hais tias lawv yog ob qho tib si kev lag luam muaj nyob rau hauv cov kev daws teeb meem uas yooj yim diluted, qhov concentration ntawm cov tshuaj "concentrated" tsis paub meej.

Vim li cas Rutherford tus qauv hu ua tus qauv nuclear?
Rutherford tus qauv ntawm lub atom yog hu ua nuclear atom vim nws yog thawj atomic qauv los feature lub nucleus ntawm nws cov tub ntxhais
Tus qauv ntsuas kub thiab siab yog dab tsi Vim li cas tus qauv tsim nyog?
Cov txheej txheem siv cov txheej txheem yog qhov tseem ceeb rau kev qhia txog cov kua dej ntws thiab qhov ntim ntawm cov kua thiab cov pa roj, uas yog nyob ntawm qhov kub thiab txias. STP feem ntau yog siv thaum cov txheej txheem hauv xeev raug siv rau kev suav
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Vim li cas cov qauv ntawm cov dej ua rau nws muaj cov kuab tshuaj zoo?
Dej muaj peev xwm yaj ntau yam khoom sib txawv, uas yog vim li cas nws yog ib qho hnyav hnyav. Cov dej molecules muaj lub ntsiab lus ntawm cov pa oxygen thiab hydrogen atoms - ib sab (hydrogen) muaj qhov zoo hluav taws xob thiab lwm sab (oxygen) muaj qhov tsis zoo
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
