Nyiaj tsis yog teb nrog rau dilute cov kua qaub los yog dej, tab sis nws tsis kam nrog oxygen.
Yog li ntawd, cov nyiaj puas ua rau dilute sulfuric acid?
Cov khoom siv tshuaj Silver ua tsis yog react nrog dilute hydrochloric kua qaub thiab dilute sulfuric acid tab sis nws reacts nrog kub concentrated sulfuric acid thiab qhov no tshuaj tiv thaiv muab sulfur dioxide dej thiab nyiaj sulfate. Silver reacts nrog ob leeg dilute thiab concentrated nitric kua qaub ua form nyiaj nitrate.
Kuj Paub, yuav ua li cas tshwm sim thaum hlau react nrog dilute acids? Thaum a hlau reacts nrog dilute acid , ntsev yog tsim. Lub sijhawm no tshuaj tiv thaiv hydrogen gas yog evolved. Hauv lwm lo lus, thaum a hlau yog ntxiv rau dilute cov kua qaub , ntsev thiab hydrogen gas yog tsim. Sulfate ntsev thiab chloride ntsev yog tsim thaum hlau react nrog dilute sulfuric kua qaub thiab hydrochloric kua qaub.
Tsuas yog li ntawd, puas muaj cov poov tshuaj tiv thaiv nrog dilute acid?
Potassium reacts nrog dilute hydrochloric kua qaub muab poov tshuaj chloride thiab hydrogen gas.
Yuav ua li cas sodium react nrog dilute acid?
Sodium reacts nrog dilute hydrochloric kua qaub ua form sodium chloride thiab hydrogen gas. Kev sib xyaw ua ke nrog dej tsim sodium hydroxide. Hydrogen gas yog tsim thaum lub sij hawm tshuaj tiv thaiv thiab cov tshuaj alkaline yog tsim hu ua sodium hydroxide.

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 cov hlau tsis ua rau cov kua qaub?
Feem ntau, cov non-metals tsis hnov mob nrog dilute acids. Qhov no yog vim hais tias thaum ib yam khoom reacts nrog acids, nws muab electrons rau H + ions uas ua los ntawm cov kua qaub. Cov hlau tsis muaj hlau yuav nquag tsis hnov mob nrog dej, txawm li cas los xij, cov hlau tsis yog hlau oxides yuav hnov mob nrog dej los tsim cov kua qaub
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
Yuav ua li cas rau pH Thaum cov kua qaub ntxiv rau alkali?
Ntxiv dej rau cov kua qaub los yog lub hauv paus yuav hloov nws cov pH. Cov kua qaub los ua acidic tsawg. Ib yam li ntawd, thaum alkali diluted nrog dej, qhov concentration ntawm OH - ions txo. Qhov no ua rau pH ntawm alkali poob ntawm 7, ua rau cov tshuaj tsawg alkaline raws li cov dej ntxiv ntxiv
