Kuchokera pansi mpaka pamwamba pa tebulo zazitsulo

  • Wonjezerani pakukonzanso
  • Kutaya ma elekitironi (oxidize) mosavuta kuti apange ayoni abwino
  • Kuwononga kapena kuwononga mosavuta
  • Amafuna mphamvu zambiri (ndi njira zosiyanasiyana) kuti atalikirane ndi mankhwala awo
  • Khalani othandizira ochepetsa (othandizira ma electron).

Kusintha ndi madzi ndi zidulo

Zitsulo zotakasika kwambiri, monga sodium, zimayankha ndi madzi ozizira kuti apange hydrogen ndi iron hydroxide:

2Na + 2H2O => 2NaOH + H2

Zitsulo pakati pazoyesereranso, monga chitsulo, zimayankha ndi zidulo monga sulfuric acid (koma osati madzi kutentha kwenikweni) kupatsa hydrogen ndi mchere wachitsulo, monga iron (II) sulphate:

Fe + H2SO4 => FeSO4 + H2

Kusintha kosakwatira kamodzi

Msomali wachitsulo mu njira yamkuwa ya sulphate amatha kusintha mtundu posachedwa mkuwa wachitsulo wokutidwa ndi sulphate yachitsulo (II).

Fe + CuSO4 => Cu + FeSO4

Nthawi zambiri, zilizonse zazitsulo zomwe ndizocheperako pazoyambiranso zimatha kusinthidwa ndi chitsulo: zitsulo zazitali zimachepetsa ayoni wazitsulo. Izi zimagwiritsidwa ntchito popanga ma thermite popanga chitsulo chazitsulo pang'ono komanso pokonza titaniyamu ndimachitidwe a kroll (Ti ili pafupifupi mulingo wofanana ndi Al mu reactivity series). Mwachitsanzo, okusayidi wachitsulo (III) amachepetsedwa kukhala chitsulo ndipo okusayidi ya aluminium amasinthidwa motere.

2Al + Fe2O3 -> 2Fe + Al2O3

Momwemonso, kuchotsa titaniyamu kuchokera ku tetrachloride kungapezeke pogwiritsa ntchito magnesium, yomwe pamapeto pake imapanga magnesium chloride:

2Mg + TiCl4 => Ti + 2MgCl2

Zina zimatha kugwiranso ntchito ngati potaziyamu yachitsulo itha kukonzedwa pochepetsa potaziyamu wa potaziyamu mpaka 850 ° C. Ngakhale kuti sodium mu mndandanda wa reactivity ndi yocheperapo potaziyamu, mayankhowo amatha kupitiliza popeza potaziyamu ndiyosasinthasintha ndipo kusakanikako kumathiridwa.

Na + KCl => K + NaCl

Kutsatsa kwa mafomu a ndalama kumatithandiza kukhala ndi zinthu zabwino kwambiri chifukwa chiyani tifunika kuyika zotsatsa? : D
