Video: Lub hauv paus tuaj yeem raug hu ua dab tsi?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
Bases tuaj yeem ua xa mus mus raws li: tsis muaj kev xaiv. proton txais.
OH- yog hu ua:
- hydrate ion.
- hydrogen ion.
- hydronium ion.
- hydroxide ion.
Raws li, 5 piv txwv ntawm cov hauv paus yog dab tsi?
Piv txwv ntawm Bases thiab Alkalis
- Sodium hydroxide (NaOH) los yog caustic soda.
- Calcium hydroxide (Ca (OH))2) los yog limewater.
- Ammonium hydroxide (NH4OH) los yog dej ammonia.
- Magnesium hydroxide (Mg (OH))2) los yog mis nyuj ntawm magnesia.
- Muaj ntau yam tshuaj dawb, xab npum, tshuaj txhuam hniav thiab tshuaj ntxuav.
Tom qab, lo lus nug yog, dab tsi compounds yog bases? Lub hauv paus Arrhenius yog ib yam khoom uas muab OH-, los yog hydroxide , ion thaum nws yaj hauv dej. Arrhenius acids suav nrog cov tebchaw xws li HCl, HCN, thiab H2YOG4 uas ionize hauv dej muab H+ ion. Arrhenius bases suav nrog ionic compounds uas muaj OH- ion, zoo NaOH , KOH, and Ca(OH)2.
Ntawm no, dab tsi yog lub hauv paus khoom?
A puag yog a yam khoom uas txais hydrogen ions. Thaum a puag yog yaj hauv dej, qhov sib npaug ntawm hydrogen ions thiab hydroxide ions hloov mus rau qhov sib txawv. Vim lub puag "soaks" hydrogen ions, qhov tshwm sim yog kev daws nrog ntau hydroxide ions dua li hydrogen ions.
Base siv rau dab tsi?
Khoom thiab Piv txwv ntawm Bases Bases nyiam saj iab thiab xav tias nplua. Hauv tsev, peb siv lub hauv paus raws li cov tshuaj ntxuav thiab ua tshuaj antacid. Cov piv txwv ntawm hauv paus pom hauv tsev muaj xws li xab npum; lye, uas muaj nyob rau hauv qhov cub ntxuav, piv txwv li; mis nyuj ntawm magnesia; and Tug.

Lub cav puas tuaj yeem muaj lub hauv paus tsis zoo?
Yog li, kev ua haujlwm exponential nrog lub hauv paus tsis zoo, xws li tsis yog ntau ntawm kev ua haujlwm ntawm tag nrho (nws tsis tas li), vim nws tsuas tuaj yeem ntsuas ntawm qhov tshwj xeeb x-tus nqi. Nws yog vim li no uas peb tsuas yog xav txog logarithms nrog cov hauv paus zoo, vim cov hauv paus tsis zoo tsis tas mus li thiab feem ntau tsis muaj txiaj ntsig
Muaj pes tsawg lub hauv paus zoo tuaj yeem muaj qhov sib npaug?
Ib txoj hauv kev los txiav txim siab qhov siab tshaj plaws ntawm qhov zoo thiab qhov tsis zoo ntawm cov hauv paus ntsiab lus ntawm polynomial. Txij li thaum muaj peb qhov kev hloov pauv, muaj qhov siab tshaj plaws ntawm peb lub hauv paus zoo
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
Koj puas tuaj yeem muab lub voos xwmfab hauv paus los ntawm lub hauv paus square?
Cov Khoom Muag tau nce mus rau Txoj Cai Fais Fab yog qhov tseem ceeb vim tias koj tuaj yeem siv nws los faib cov lus qhia radical. Nco ntsoov tias cov hauv paus hniav zoo ib yam - koj tuaj yeem muab cov hauv paus plaub hau nrog cov hauv paus plaub hau, lossis cov hauv paus hniav nrog lub voos xwmfab, piv txwv li. Tab sis koj tsis tuaj yeem muab lub hauv paus square thiab lub voos xwmfab hauv paus siv txoj cai no
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
