base, hauv chemistry, txhua yam khoom uas nyob rau hauv cov kua dej yog nplua rau qhov kov, saj iab, hloov xim ntawm cov ntsuas(piv txwv li, tig liab litmus ntawv xiav), reacts nrog acids los tsim cov ntsev, thiab txhawb qee cov tshuaj tiv thaiv kab mob (base catalysis).
Pib piv txwv hauv chemistry yog dab tsi?
Piv txwv ntawm cov hauv paus yog sodium hydroxide, calcium carbonate thiab potassium oxide. Lub hauv paus yog ib yam khoom uas muaj peev xwm neutralize cov kua qaub los ntawm reacting nrog hydrogen ions. Feem ntau cov hauv paus yog cov zaub mov uas ua rau cov kua qaub los ua dej thiab ntsev.
Dab tsi yog cov kua qaub lossis lub hauv paus?
An acid yog ib yam khoom uas pub cov protons (hauv Brønsted-Lowry txhais) lossis lees txais ib khub valence electrons los ua ib daim ntawv cog lus (hauv Lewis txhais). Lub hauv paus yog ib yam khoom uas tuaj yeem txais tau cov protons lossis pub ib khub ntawm valence electrons los ua ib daim ntawv cog lus. Cov hauv paus tuaj yeem xav tias yog cov tshuaj sib txawv ntawm cov kua qaub.
Pib hauv chemistry pH yog dab tsi?
Qhia ntxaws. pH yog ib qho kev ntsuas ntawm acidic/basic dej. Qhov ntau yog los ntawm 0 - 14, nrog 7 yog nruab nrab. pH tsawg dua 7 qhia tias acidity, whereas a pH ntau dua 7 qhia tias lub hauv paus.
Dab tsi ua rau qee yam hauv paus hauv chemistry?
Ib lub hauv paus yog khoom uas lees txais hydrogen ions Thaum lub hauv paus yog yaj hauv dej, qhov sib npaug ntawm hydrogen ions thiab hydroxide ions hloov mus rau qhov sib txawv. Vim tias lub hauv paus "soaks" hydrogen ions, qhov tshwm sim yog kev daws teeb meem nrog ntau hydroxide ions dua li hydrogen ions.
