  • Kordhi falcelinta
  • Lumitaanka elektaroonigga (oksaydh) si fudud oo fudud si ay u sameeyaan ion togan
  • Si fudud u nadiifi ama u sumee
  • U baahan tamar dheeraad ah (iyo habab kala duwan) si looga faquuqo xeryahooda
  • Noqo wakiilo yarayn kara (deeq bixiyaasha elektarooniga).

Falcelinta biyaha iyo asiidhyada

Biraha ugu falcelinta badan, sida sodium, waxay ku falcelin doonaan biyo qabow si loo soo saaro hydrogen iyo biraha hydroxide:

2Na + 2H2O => 2NaOH + H2

Biraha dhexda taxanaha falcelinta, sida birta, waxay ku falcelin doontaa asiidhyada sida sulfuric acid (laakiin maaha biyo heerkulka caadiga ah) si loo siiyo haydrojiin iyo milix cusbo, sida birta (II) sulfate:

Fe + H2SO4 => FESO4 + H2

Falcelinta barakaca oo keli ah

Ciddiyaha birta ee xalka sulphate copper ayaa si dhakhso leh u beddeli kara midabka maaddaama naxaasta macmalka ah ay ku dahaadhan tahay birta (II) sulphate

Fe + CuSO4 => Cu + FESO4

Guud ahaan, mid kasta oo ka mid ah biraha ka yar taxanaha falcelinta waxaa lagu beddeli karaa bir: biraha sare waxay yareeyaan ion birta hoose. Tan waxaa loo isticmaalaa fal-celinta kuleylka ee soo-saarista qaddar yar oo bir ah oo macdan ah iyo diyaarinta titanium habka kroll (Ti qiyaastii waa isku heer Al oo ah taxanaha falcelinta). Tusaale ahaan, birta (III) oksaydhku waxay ku yaraatay birta iyo aluminium oksaydh ayaa loo beddelay hawshan.

2Al + Fe2O3 -> 2Fe + Al2O3

Sidoo kale, ka saarida titanium-ka tetrachloride waxaa lagu gaari karaa iyadoo la adeegsanayo magnesium, kaasoo ugu dambeeya qaabeeya magnesium chloride:

2Mg + TiCl4 => Ti + 2MgCl2

Waxyaabaha kale ayaa laga yaabaa, si kastaba ha noqotee, inay soo galaan ciyaarta maadaama macdanta macdanta loo diyaarin karo iyada oo la yareeyo sodium potassium chloride ilaa 850 ° C. In kasta oo sodium ku jirta taxanaha falcelintu ay ka yar tahay potassium, falcelintu way sii socon kartaa maaddaama ay potassium is bedbeddelayso oo isku darka la dhalaalinayo

Na + KCl => K + NaCl
