Isingeniso

Iodine iyikhemikhali enophawu lwekhemikhali I kanye nenombolo ye-athomu engu-53. Iodine isakhi esingeyona insimbi evame ukutholakala emvelweni olwandle nasenhlabathini. Okulandelayo incazelo yemvelo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha kwe-iodine:

 

1. Imvelo:

-Ukubukeka: Iodine iyikristalu eluhlaza okwesibhakabhaka-mnyama, evamile esimweni esiqinile.

-Iphuzu lokuncibilika: I-iodine ingashintsha ngokuqondile isuka esimweni esiqinile iye kwesegesi ngaphansi kwezinga lokushisa lomoya, elibizwa ngokuthi i-sub-limation. Iphuzu layo lokuncibilika licishe libe ngu-113.7 ° C.

-Iphuzu lokubilisa: Iphuzu elibilayo le-Iodine ekucindezelweni okujwayelekile licishe libe ngu-184.3 ° C.

-Ukuminyana: Ukuminyana kwe-Iodine cishe ku-4.93g/cm³.

-Ukunyibilika: Iodine ayincibiliki emanzini, kodwa iyancibilika kwezinye izincibilikisi eziphilayo ezifana notshwala, i-cyclohexane, njll.

 

2. Sebenzisa:

-Inkundla yezemithi: Iodine isetshenziswa kakhulu ekubulaleni amagciwane kanye nokuvalwa inzalo, futhi ivamise ukutholakala ekubulaweni kwamagciwane esilondeni kanye nemikhiqizo yokunakekelwa ngomlomo.

-Imboni yokudla: Iodine yengezwa njenge-Iodine kusawoti wetafula ukuvimbela izifo zokuntuleka kwe-iodine, njenge-goiter.

-Ukuhlolwa kwamakhemikhali: Iodine ingasetshenziswa ukuthola ukuba khona kwesitashi.

 

3. Indlela yokulungiselela:

- Iodine ingakhishwa ngokushisa izimila zasolwandle, noma ngokukhipha insimbi ene-iodine ngokusabela kwamakhemikhali.

-Ukusabela okujwayelekile kokulungiswa kwe-Iodine ukusabela kwe-Iodine nge-oxidizing agent (njenge-hydrogen peroxide, i-sodium peroxide, njll.) ukuze kukhiqizwe i-iodine.

 

4. Ulwazi Lokuphepha:

- Iodine ingase icasule isikhumba namehlo lapho kugxilwe kakhulu, ngakho-ke udinga ukunaka ukusetshenziswa kwezinto zokuzivikela, njengamagilavu ​​kanye nezibuko, lapho uphatha i-Iodine.

- Iodine inobuthi obuphansi, kodwa kufanele igweme ukudla ngokweqile i-iodine ukuze ugweme ubuthi be-iodine.

- Iodine ingakhiqiza igesi ye-Iodine hydrogen enobuthi ezingeni lokushisa eliphezulu noma ilangabi elivulekile, ngakho gwema ukuthintana nezinto ezivuthayo noma ama-oxidants.
