Nws yog siv rau txiav txim siab cov khoom ntawm ib qho kev hloov pauv hloov, uas yog hlau A yuav hloov lwm cov hlau B hauv kev daws yog tias A siab dua hauv qhov series . Kev ua yeeb yam series ntawm ib co ntawm ntau hom hlau, teev nyob rau hauv descending kev txiav txim ntawm reactivity.

Ib yam li ntawd, qhov kev ua yeeb yam yog dab tsi thiab nws ua haujlwm li cas?

Cov kev ua haujlwm ntawm cov hlau yog ib qho cuab yeej siv los kwv yees cov khoom hauv hloov chaw cov tshuaj tiv thaiv thiab reactivity ntawm hlau nrog dej thiab acids nyob rau hauv kev hloov cov tshuaj tiv thaiv thiab ore extraction. Nws tuaj yeem siv los kwv yees cov khoom lag luam zoo sib xws nrog cov hlau sib txawv.

Tsis tas li ntawd, vim li cas cov kev ua haujlwm series ua haujlwm? Kev Ua Haujlwm Series . Lub peev xwm ntawm ib lub ntsiab lus teb nrog lwm lub ntsiab lus yog npe nws kev ua si . Qhov yooj yim dua yog rau ib lub ntsiab lus teb nrog lwm cov khoom, qhov ntau dua nws kev ua si . Rau cov hlau, qhov loj dua kev ua si , qhov yooj yim dua lawv poob electrons, tsim cov ions zoo.

Tsis tas li ntawd, cov hlau reactivity series ua haujlwm li cas?

Cov hlau reactivity series cov npe hlau nyob rau hauv kev txiav txim ntawm lawv reactivity , los ntawm siab tshaj mus rau qis tshaj los ntawm sab saum toj mus rau hauv qab. A hlau teev saum toj no lwm tus hlau yuav hloov qhov ntawd hlau nyob rau hauv ib qho kev hloov pauv (ib qho kev hloov pauv) cov tshuaj tiv thaiv.

Dab tsi yog kev ua yeeb yam series Nws pab peb li cas hauv kev kwv yees?

Ib tug hlau muab tso rau saum hydrogen nyob rau hauv lub kev ua yeeb yam series yuav tshem tawm hydrogen los ntawm dej los yog acids. Ib tug hlau muab tso rau saum lub kev ua yeeb yam series tshem cov hlau hauv qab nws. Yog li, ib qho hlau reactive dua displaces ib tug tsawg reactive hlau los ntawm nws cov ntsev tov.
