Feem ntau, cov tsis yog - hlau ua tsis yog teb nrog dilute kua qaub . Qhov no yog vim thaum muaj khoom reacts nrog acids , nws muab electrons rau H + ions tsim los ntawm lub kua qaub . Tsis yog - hlau yuav ib txwm tsis teb Txawm li cas los xij, nrog dej, tsis yog - hlau oxides yuav teb nrog dej kom tsim kua qaub.

Kuj nug, yog vim li cas cov hlau tsis hnov mob nrog cov kua qaub?

Tsis yog - hlau tsis feem ntau react nrog acids vim tias thaum muaj khoom, reacts nrog acids nws muab electrons rau $$H+$$ ions uas tsim los ntawm tus kua qaub . Tsis yog - hlau yog txais ntawm electrons thiab li no, lawv ua tsis tau pub nyiaj electrons.

Tsis tas li ntawd, yuav ua li cas tshwm sim thaum uas tsis yog hlau oxide reacts nrog acid? Tsis yog - Cov tshuaj tiv thaiv hlau Oxide Cov oxides ntawm tsis yog - hlau yog acidic . Yog ib tsis yog - hlau oxide dissolves nyob rau hauv dej, nws yuav tsim ib tug kua qaub . Cov tsis yog - hlau oxides tuaj yeem neutralized nrog lub hauv paus los tsim cov ntsev thiab dej.

Tsis tas li ntawd, puas yog hlau tsis kam nrog lub hauv paus?

Lawv react nrog bases tsim cov ntsev thiab dej. Cov tshuaj tiv thaiv ntawm lwm yam tsis yog - hlau nrog hauv paus ua tau heev complex. Tsis yog - hlau oxides feem ntau yog acidic nyob rau hauv cov xwm thiab react nrog bases tib yam li cov kua qaub (ntsev thiab dej).

Yuav ua li cas tshwm sim thaum ib tug tsis yog hlau reacts nrog ib tug uas tsis yog hlau?

Thaum a hlau reacts nrog ib tug tsis - hlau nws tsim ib daim ntawv cog lus ionic. Piav: Thiab Tsis yog - hlau yog lub ntsiab lus opposite; Lawv muaj ib tug nyiam mus nce electrons thiab tsim tsis zoo ions (anions).

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

Puas yog Phosphorus yog hlau lossis tsis yog hlau?

Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob

Puas muaj zog npaum li cas yog cov kua qaub los yog cov hauv paus daws teeb meem?

Qhov ntau ntawm 0 mus rau 14 muab kev ntsuas ntawm kev sib piv lub zog ntawm cov kua qaub thiab cov hauv paus daws teeb meem. Cov dej ntshiab thiab lwm cov kev daws teeb meem nruab nrab muaj tus nqi pH ntawm 7. Tus nqi pH tsawg dua 7 qhia tias cov kua qaub yog acidic, thiab pH tus nqi ntau dua 7 qhia tias cov tshuaj yog qhov yooj yim

Cov tshuaj ntxuav qhov cub puas yog cov kua qaub lossis cov hauv paus?

Ntau yam khoom siv tu, xws li xab npum thiab qhov cub ntxuav, yog cov hauv paus. Bases neutralize (tso tawm) acids. Alkalis yog cov hauv paus uas yaj hauv dej. Qhov ntau hydroxide ions ib lub hauv paus muaj, nws muaj zog dua
