CHEMISTRY GLOSSARY Cov khoom nruab nrab yog ib yam khoom uas tsis qhia cov kua qaub lossis cov khoom hauv paus, muaj cov lej sib npaug ntawm hydrogen thiab hydroxyl ions thiab tsis hloov xim ntawm litmus-daim ntawv.
Vim li cas qee yam tshuaj tsis muaj tseeb?
Qee cov tshuaj nruab nrab yog tsim thaum cov kua qaub sib xyaw nrog lub hauv paus thiab cov tshuaj tiv thaiv neutralization tshwm sim Lwm yam tshuaj tsis muaj qab hau pib nrog. Lawv tsis yog cov khoom ntawm cov tshuaj tiv thaiv neutralization. Cov khoom nruab nrab uas paub zoo tshaj plaws yog: dej, rooj ntsev, kua qab zib thiab roj ua noj.
Dab tsi yog hu ua cov khoom nruab nrab?
Cov tshuaj uas tsis pom kev hloov xim nrog daim ntawv litmus yog hu ua cov khoom nruab nrab. Cov tshuaj no tsis yog acidic lossis yooj yim. Piv txwv li, ntsev, ammonium chloride, calcium chloride, sodium carbonates, sodium bicarbonates thiab lwm yam.
Dab tsi yog cov kua qaub thiab cov khoom nruab nrab?
Ib qho kua qaub yog ib yam khoom uas nws qib pH tsawg dua 7. Base yog ib yam khoom uas nws qib pH ntau dua 7. Cov khoom nruab nrab yog cov khoom uas nws qib pH yog 7.
Neutral acids yog dab tsi?
pH yog ntsuas seb cov kua qaub / cov dej hauv paus yog li cas. Qhov ntau yog los ntawm 0 - 14, nrog 7ua nruab nrab. pH tsawg dua 7 qhia txog acidity, qhov pH ntau dua 7 qhia tias lub hauv paus. … pHs tsawg dua 7 yog acidic thaum pH ntau dua 7 yog alkaline (basic).
