Ib ACID yog ib yam khoom uas yaj hauv dej los tsim cov khoom zoo hu ua hydrogen ions (H+). Cov rov qab ntawm kua qaub yog ib ALKALI uas yaj hauv dej los tsim cov ions tsis zoo ntawm hydrogen thiab oxygen hu ua hydroxide ions (OH-). Alkalis yog ANTI AIDS vim lawv tshem tawm acidity.

Kuj nug, yog acid qhov opposite ntawm alkaline?

Feem ntau siv lus lus ntawm kua qaub isalkali, ntawm acidic yog alkaline . Raws li koj hais, kua qaub / acidic xa mus rau pH tsawg dua 7, alkali / alkaline pH ntau dua 7, thiab nruab nrab rau pH sib npaug rau 7.

Ib sab saum toj, dab tsi yog acid thiab alkaline? Cov kua qaub muaj pH tsawg dua 7. Alkalis havea pH ntau dua 7 Cov khoom nruab nrab muaj pH sib npaug rau 7. Cov kua qaub muaj ntau cov hydrogen ions, uas muaj lub cim H +. Alkalis muaj ntau cov hydroxide ions, cim OH-. Dej yog nruab nrab vim hais tias tus naj npawb ntawm hydrogen ions sib npaug rau cov hydroxide ions.

Tsis tas li ntawd, qhov txawv ntawm cov kua qaub thiab alkali yog dab tsi?

Qhov sib txawv ntawm cov kua qaub , alkali , andbases: Cov kua qaub yog cov tshuaj uas muaj pH tsawg dua 7.0, thaum lub hauv paus yog cov khoom uas muaj pH ntau tshaj 7.0. Ib cov piv txwv ntawm cov hauv paus yog sodium hydroxide, potassium hydroxide, thiab lwm yam. Cov kua qaub feem ntau saj qaub, thaum lub hauv paus muaj abitter saj.

Vim li cas alkalis tau piav raws li qhov sib txawv ntawm cov kua qaub?

Bases yog cov khoom uas cuam tshuam nrog kua qaub andneutralise lawv. Copper oxide yog lub hauv paus vim nws yuav hnov mob nrog kua qaub thiab neutralize lawv, tab sis nws tsis yog ib qho alkali vim nws tsis yaj hauv dej. Sodium hydroxide yog ib lub hauv paus vim nws yuav hnov mob nrog kua qaub thiab neutralisethem.
