Feem ntau, bases tsis hnov tsw nrog hlauthiab tso cov roj hydrogen.
Yuav ua li cas thaum lub hauv paus hnov mob nrog hlau?
Ib puag ncig nrog cov hlau ua ntsev Thaum lub sij hawm cov tshuaj tiv thaiv ntawm lub hauv paus nrog hlau, hydrogen gas yog hloov zuj zus. Cov evolution ntawm hydrogen roj tuaj yeem lees paub los ntawm kev nqa lub teeb taws tswm ciab ze ntawm lub qhov ncauj ntawm lub raj ntsuas. Qhov no ua rau lub suab nrov, qhia txog kev hloov pauv ntawm cov pa roj hydrogen.
Vim li cas cov hauv paus tsis hnov mob nrog hlau?
Lawv tsis hnov qab vim hlau muaj cov yam ntxwv yooj yim, piv txwv li lawv ua rau muaj kev cuam tshuam nrog h20 lossis o2. Cov hlau feem ntau tsis hnov mob nrog cov hauv paus tab sis zinc hlau ua vim nws yog amphoteric.
Vim li cas cov hauv paus ua rau cov hlau?
Metals react with base raug muab hlau ntsev thiab hydrogen gas. Hlau zoo li zinc reacts nrog sodium hydroxide los tsim cov roj hydrogen. Piv txwv li, zinc reacts nrog sodium hydroxide muab sodium zincate.
Puas yog cov hlau?
Ib lub hauv paus yog li ntawd hlau hydroxide xws li NaOH lossis Ca(OH) 2 Cov tshuaj aqueous hydroxide kuj tau piav qhia los ntawm qee yam. yam ntxwv zoo. Lawv nplua rau qhov kov, tuaj yeem saj iab thiab hloov xim ntawm pH ntsuas (piv txwv li, tig liab litmus ntawv xiav).
