Daim ntawv teev cov tsev neeg Bases & Acids
- Baking Soda. Baking soda yog qhov sib Lub npe rau sodium bicarbonate, paub tshuaj raws li NaHCO3.
- Diluted Soaps.
- Tsev neeg Ammonia.
- Tsev neeg Vinegars.
- Citric Acid .
Hauv qhov no, qee cov kua qaub hauv tsev yog dab tsi?
Qee cov khoom siv hauv tsev uas muaj cov kua qaub muaj xws li: yogurt, vinegar , kua txiv qaub , citric acid, txiv apples, jelly, pineapples, cranberry sauce, mis nyuj, thiab roj teeb.
Ib tug kuj yuav nug, dab tsi yog lub hauv paus hauv tsev? Ib tsev neeg tshuaj hauv paus xws li ammonia, ci dej qab zib thiab lye.
Ntawm no, dab tsi yog 10 cov kua qaub hauv tsev?
- Carbonic acid (cov dej qab zib)
- Vinegar (acetic acid)
- Roj teeb acid (sulfuric acid)
- Citric acid (txiv qaub)
- Tartaric Acid (tamarind: ua noj)
- Lactic acid (kua mis, yohgurt)
- hydrochloric acid (siv raws li tin soldering flux)
- Shampoo (salicylic acid) thiab lwm yam.
Dab tsi yog 5 lub hauv paus?
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)

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 qhov txawv ntawm cov kua qaub thiab cov hauv paus ntawm pH nplai?
Distinguishing ntawm acids thiab bases. Keydifference: Acids thiab bases yog ob hom tshuaj corrosive. Txhua yam khoom uas muaj pH tus nqi nruab nrab ntawm 0 txog 7 yog suav tias yog acidic, qhov apH tus nqi ntawm 7 txog 14 yog lub hauv paus. Cov kua qaub yog cov ioniccompounds uas sib cais hauv dej los tsim cov hydrogen ion (H +)
Peb siv cov kua qaub thiab cov hauv paus hauv lub neej txhua hnub li cas?
Cov tshuaj txhuam hniav thiab tshuaj tiv thaiv kab mob yog cov piv txwv zoo ntawm cov khoom lag luam thaum cov khoom noj xws li kua txiv kab ntxwv lossis txiv kab ntxwv yog cov kua qaub heev. Qhov ntsuas pH. Lub pH nplai khiav los ntawm 1 txog 14 thiab qhia txog ntau yam ntawm cov kua qaub thiab cov hauv paus ntawm sab saum toj mus rau hauv qab. Tshuaj txhuam hniav thiab pH. pH ntawm cov khoom noj khoom haus. Acid Neutralizing Tshuaj. Cov khoom siv ntxuav
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
Cov tshuaj tiv thaiv hu ua dab tsi thaum cov kua qaub reacts nrog lub hauv paus?
Cov tshuaj tiv thaiv ntawm cov kua qaub nrog lub hauv paus yog hu ua cov tshuaj tiv thaiv neutralization. Cov khoom ntawm cov tshuaj tiv thaiv no yog ntsev thiab dej. Piv txwv li, cov tshuaj tiv thaiv ntawm hydrochloric acid, HCl, nrog sodium hydroxide, NaOH, cov kev daws teeb meem tsim cov tshuaj sodium chloride, NaCl, thiab qee cov dej molecules ntxiv
