Tsev neeg hauv paus
Lwm yam khoom nyob ib ncig ntawm lub tsev uas muaj hauv paus muaj xws li Ammonia, dej huv, ci dej qab zib, chalk, tshuaj txhuam hniav, Windex, tshuaj dawb, ntxhua khaub ncaws, tshuaj zawv plaub hau, thiab qe dawb.
Ib qho ntxiv, qee lub hauv paus hauv tsev yog dab tsi?
Cov khoom siv tshuaj hauv tsev muaj xws li ammonia, baking soda thiab lye
- Baking Soda. Baking soda, los yog sodium bicarbonate (NaHCO3) muaj pH ntawm 8.3, siab tshaj dej distilled pH ntawm 7.0.
- Borax: ntxuav thiab tshuaj tua kab.
- Mis nyuj ntawm Magnesia (Magnesium Hydroxide)
- Ammonia, yeeb ncuab ntawm av.
- Lye: Clog Buster.
Tsis tas li ntawd, 5 lub hauv paus yog dab tsi? Qee qhov muaj zog Arrhenius muaj xws li:
- Potassium hydroxide (KOH)
- Sodium hydroxide (NaOH)
- Barium hydroxide (Ba(OH))2)
- Cesium hydroxide (CsOH)
- Strontium hydroxide (Sr (OH))2)
- Calcium hydroxide (Ca (OH))2)
- Lithium hydroxide (LiOH)
- Rubidium hydroxide (RbOH)
Tom qab ntawd, lo lus nug yog, dab tsi yog qee qhov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus?
Daim ntawv teev cov tsev neeg Bases & Acids
- Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3.
- Diluted Soaps.
- Tsev neeg Ammonia.
- Tsev Neeg Vinegar.
- Citric Acid.
Lub hauv paus yog dab tsi?
Hauv chemistry, a puag yog ib hom tshuaj uas pub electrons, txais cov protons, lossis tso tawm hydroxide (OH-) ions hauv cov kua dej. Hom ntawm hauv paus suav nrog Arrhenius puag , Brosted-Lowry puag , thiab Lewis puag.
Pom 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
Dab tsi yog qee cov kua qaub hauv tsev thiab cov hauv paus?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
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
Cov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus yog dab tsi?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
Dab tsi yog lub hauv paus ntsiab lus ntawm txoj kev xav ntawm lub neej tiam neeg?
Txoj kev xav ntawm lub neej tiam neeg tau hais tias muaj sia nyob tuaj yeem tshwm sim los ntawm cov khoom tsis muaj sia nyob thiab cov txheej txheem zoo li no tau tshwm sim thiab tsis tu ncua. Piv txwv li, nws tau xav tias qee yam xws li fleas tuaj yeem tshwm sim los ntawm cov khoom tsis muaj tsiaj xws li hmoov av, lossis cov maggots tuaj yeem tshwm sim los ntawm cov nqaij tuag
