Ohan yak qator payvastagihoi khosiyathoi gunogundoshtaro ho- sil mekunad. Oksidi ohan (II) GeO dar natijai nopurra barqaror kardani magnetit Ge3O4 bo oksidi karbon (II) SO hosil karda me- shavad.
Ge3O4 +SO = 3GeO + SO2$
GeO – moddai siyohi khokamonandi oson oksidshavanda, dar ob va ishqorho halnashavanda ast. Bo tasiri kislotaho namakhoi muvofiqro hosil mekunad.
GeO + 2NS1 = GeS12 + N2O
Gidroksidi ohan (II). Ba oksidi GeO gidroksidi Ge(ON)2 muvofiq meoyad, ki onro bo tasiri ishqorho az namakhoi ohani (II) hosil mekunand:
GeS12 + 2\aO11 = Ge(ON)2 4 + 2№S1
Ge(ON)2 moddai rangash safed buda, khosiyati asosi dorad. Bo kislotaho ba osoni ba reaksiya dokhil meshavad.
Ge(ON)2 + 2NS1 = GeS12 + 2N2O;
Ge(ON)2 + 2SN3SOON = Ge(SN3SOO)2 + 2N2O.
Namakhoi ohan (II) monandi ionhoi gidratnokshuda rangi sab- zi ravshanro dorand. Ge(ON)2 dar havo oksid shuda, rangi khoki- stariro girifta, ba Ge(ON)3 tabdil meyobad:
4Ge(ON)2 + O 2 + 2N2O = 4Ge(ONu
Oksidi ohan (III) Ge2O3 – in modda rangi surkhi jigari doshta, dar ob hal nameshavad. Onro dar natijai suzishi kolchedani ohan (pirit) hosil mekunand.
Ge2O3 khosiyati zaifi amfoteri dorad. Bo tasiri kislotaho namakhoi ohan (III), bo tasiri ishqorho namakhoe, ki ohan mis- li boqimondai kislotagi ast, hosil mekunad.
Ge2O3 + 6NS1 = 2GeS13 + 3N2O;
Ge2O3 + 2\aO11 = 2\aGsO. + N2O.

Gidroksidi ohan (III) Ge(ON)3 misli Ge(ON)2 asos buda, kho- siyati on zaiftar meboshad. Binobar in, namakhoi ohan (II) dar mahlul kam gidroliz meshavand, vale namakhoi ohan (III) chunon ziyod gidroliz meshavand, ki to ba hosil shudani zarrahoi kol- loidii gidroksidi ohan (III) meovarad.
Dar ishtiroki kislotahoi serob Ge(ON)3 namakhoi muvofiqro ba osoni hosil mekunad. Namakhoi ohan (III) bo tiosianati kaliy (rodanit) ba reaksiya dokhil shuda, namaki kompleksii rangi sur- khi ba khun monandro hosil mekunad. In reaksiya baroi namakhoi ohani (III) reaksiyai sifati ba shumor meravad:
GeS13 + ZKSA^ = Ge(S^)3 + 3KS1
Hangomi ba Ge(ON)3 tasir namudani mahluli konsentronidai ishqorho payvastagihoi ustuvori kompleksiro hosil mekunad:
Ge(ON)3 + 3KON = K3[Ge(ON)6]
Az bayni namakhoi ohan kuporosi ohan Ge8O4.7N2O az hama beshtar ba kor burda meshavad. Baroi peshgiri kardani pusishi chub onro dar mahluli kuporosi ohan yakchand muddat tar mekunand. Kuporosi ohanro dar istehsoli rangho niz istifoda mebarand.
Ohan ba tarkibi organizmi rustani va hayvonot dokhil mesha- vad. Vay dar gemoglobini khun mavjud ast, ki oksigenro az shush ba boftaho meovarad. Dar tarkibi khlorofill ohan vujud nadorad, ammo baroi dar rustaniho ba vujud omadani khlorofill zarur ast. Agar dar khok ohan kami kunad, rustaniho khlorofillro ba vujud nameorand va rangi sabzashon nopadid meshavad.
