Kuenda kubva pasi kusvika kumusoro kwetafura simbi

  • Wedzera mukuita zvekare
  • Rasa maerekitironi (oxidize) nyore nyore kuti ugadzire akanaka maion
  • Kukanganisa kana kushatisa zviri nyore
  • Inoda simba rakawanda (uye nzira dzakasiyana) kuti isarudzwe kubva kumakomponi avo
  • Iva akasimba ekuderedza vamiririri (maelektroni vanopa).

Reaction nemvura uye acids

Iyo simbi inoshanda zvakanyanya, senge sodium, ichaita nemvura inotonhorera kugadzira hydrogen nesimbi hydroxide:

2Na + 2H2O => 2NaOH + H2

Metare pakati peiyo reactivity akateedzana, simbi, inobata nemaacid akadai sulphuric acid (asi kwete mvura pane chaiwo tembiricha) kupa hydrogen uye simbi munyu, senge iron (II) sulfate:

Fe + H2SO4 => FeSO4 + H2

Kumwe kusuduruka kwekuchinja

Chipikiri chesimbi mune yemhangura sulphate solution inogona kukurumidza kuchinja ruvara sezvo esimbi mhangura yakaputirwa nesimbi (II) sulphate.

Fe + CuSO4 => Cu + FeSO4

Kazhinji, chero simbi idzo dziri diki mune iyo reactivity akateedzana inogona kutsiviwa nesimbi: simbi dzakakwirira dzinoderedza yakaderera simbi maion. Izvi zvinoshandiswa kune iyo thermite reaction yekugadzira zvidiki zvidiki zvesimbi simbi uye yekugadzirira titanium ne kroll maitiro (Ti ingangoita yakaenzana chikamu seAl mune reactivity akateedzana). Semuenzaniso, iron (III) oxide inoderedzwa kuita simbi uye aluminium oxide inoshandurwa mune ino maitiro.

2Al + Fe2O3 -> 2Fe + Al2O3

Saizvozvowo, kubviswa kwe titanium kubva kune tetrachloride kunogona kuwanikwa uchishandisa magnesium, iyo pakupedzisira inogadzira magnesium chloride:

2Mg + TiCl4 => Ti + 2MgCl2

Zvimwe zvinhu zvinogona, zvisinei, zvikazotanga kushanda sezvo simbi potasium inogona kugadzirirwa nekudzora sodium potassium chloride kusvika ku850 ° C. Kunyange hazvo sodium mune reactivity dzakateerana iri pasi pe potassium, maitiro acho anogona kuenderera sezvo potasium isingachinjiki uye musanganiswa wakadonhedzwa.

Na + KCl => K + NaCl
