Hoʻolauna

ʻO ka Iodine kahi mea kemika me ka hōʻailona kemika I a me ka helu atomika 53. ʻO Iodine kahi mea metala ʻole i loaʻa mau ma ke ʻano i loko o ke kai a me ka lepo. Eia ka wehewehe ʻana o ke ʻano, hoʻohana, hoʻokumu a me ka ʻike palekana o Iodine:

 

1. ʻAno:

-Nani: ʻO Iodine he aniani uliuli-ʻeleʻele, maʻamau i ke kūlana paʻa.

-Ka helu hoʻoheheʻe: Hiki ke hoʻololi pololei ʻo Iodine mai ka paʻa a i ke kinoea ma lalo o ka mahana o ka ea, i kapa ʻia ʻo sub-limation. Ma kahi o 113.7 ° C kona wahi hehee.

-Wahi paila: ʻO ka helu hoʻolapalapa o Iodine ma ke kaomi maʻamau ma kahi o 184.3 ° C.

-Density: ʻO ka nui o Iodine ma kahi o 4.93g / cm³.

-Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia ka Iodine i ka wai, akā hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka waiʻona, cyclohexane, etc.

 

2. E hoʻohana:

-Pharmaceutical kahua: Hoʻohana nui ʻia ʻo Iodine no ka disinfection a me ka sterilization, a loaʻa pinepine ʻia i ka disinfection ʻeha a me nā huahana mālama waha.

-ʻOihana meaʻai: Hoʻohui ʻia ʻo Iodine e like me Iodine i ka paʻakai papa e pale ai i nā maʻi nele o Iodine, e like me ka goiter.

- Nā hoʻokolohua kemika: Hiki ke hoʻohana ʻia ka Iodine e ʻike i ka loaʻa ʻana o ka starch.

 

3. Ke ʻano hoʻomākaukau:

- Hiki ke unuhi ʻia ka Iodine ma ke puhi ʻana i ka limu, a i ʻole ma ka unuhi ʻana i ka ʻiʻo i loaʻa i ka Iodine ma o ka hopena kemika.

-ʻO kahi hopena maʻamau no ka hoʻomākaukau ʻana i ka Iodine ʻo ka hoʻopili ʻana i ka Iodine me kahi mea oxidizing agent (e like me ka hydrogen peroxide, sodium peroxide, etc.) e hana ai i ka Iodine.

 

4. ʻIke palekana:

- Hiki i ka Iodine ke hoʻonāukiuki i ka ʻili a me nā maka i nā kiʻekiʻe kiʻekiʻe, no laila pono ʻoe e hoʻolohe i ka hoʻohana ʻana i nā mea pale pilikino, e like me nā mīkina lima a me nā maka aniani, i ka wā e lawelawe ai i ka Iodine.

- He haʻahaʻa ka ʻona o ka Iodine, akā pono e pale i ka lawe nui ʻana i ka Iodine e pale aku ai i ka ʻona o Iodine.

- Hiki i ka Iodine ke hana i ka iodine hydrogen kinoea ʻona ma ka wela kiʻekiʻe a i ʻole ka lapalapa ahi, no laila e pale aku i ka hoʻopili ʻana me nā mea puhi a i ʻole nā ​​​​mea ʻona.
