Bases tsis hnov tsw nrog hlau lossis carbonates.
Yuav ua li cas thaum hlau carbonate reacts nrog puag?
Teb: Bases tsis hnov mob nrog hlau carbonates vim cov hlau carbonates muaj qhov yooj yim, yog li tsis muaj qhov tshwm sim thaum lawv hnov mob nrog cov hauv paus. Kev piav qhia: Hlau carbonates feem ntau yog hu ua bases.
Yuav ua li cas cov kua qaub tiv nrog carbonates?
Acids thiab hlau carbonates
- Thaum cov kua qaub ua rau cov carbonates, xws li calcium carbonate (pom hauv chalk, limestone thiab marble), ntsev, dej thiab carbon dioxide yog tsim.
- acid + hlau carbonate → ntsev + dej + carbon dioxide.
- sulfuric acid + hlau (II) carbonate → hlau (II) sulfate + dej + carbon dioxide.
Pob hauv paus teb nrog carbonates los ua cov pa roj carbon dioxide?
Acids hnov mob nrog carbonates ua cov pa roj carbon dioxide. … Cov carbonate ions yog qhov yooj yim. Lawv hnov mob nrog H⁺ ions los ntawm cov kua qaub xws li HCl los ua carbonic acid.
Cov kua qaub thiab cov hauv paus ua li cas nrog cov hlau carbonate?
Acids hnov mob nrog hlau carbonates lossis hlau bicarbonates muab cov pa roj carbon dioxide, nrog rau cov hlau ntsev thiab dej sib xwsSodium carbonate reacts nrog hydrochloric acid los tsim sodium chloride, carbon dioxide, thiab dej. Cov pa roj carbon dioxide no tau tso cai dhau los ntawm cov dej txiv qaub, tig nws cov kua mis.
