    Te kawe waka

    Rokiroki

    Whakaorangia ki te waahi makariri, maroke me te pouri.

    Ngā āhuatanga

    1. He ngawari te whakaheke. Te tairongo ki te marama. He tino memeha ki te wai, he memeha ki te waiwaro, he iti te wairewa ki te mewaro, me te tata korekore ki te acetone. Ko te kiato whanaunga he 4.5. Ko te ira whakarewa he 621°C. He 1280°C te ira koropuputanga. Ko te 1.7876 te taupū whakaata. He whakapataritari. Toxic, LD50 (kiore, intraperitoneal) 1400mg/kg, (kiore, waha) 2386mg/kg.

    2. Ko te Cesium iodide te ahua tioata o te hauota hauota.

    3. He kaha te waiariki Cesium iodide, engari he ngawari te waiariki e te hāora i roto i te hau makuku.

    4. Ka taea hoki te haukura iodide ki te waikura kaha penei i te konutai hypochlorite, te konutai bismuthate, te waikawa nitric, te waikawa permanganic, me te chlorine.

    5. Ko te pikinga o te wairewa o te iodine i roto i te wairewa wai o te cesium iodide na te: CsI+I2→CsI3.

    6. Ka taea e Cesium iodide te tauhohe me te pakawa hiriwa: CsI+AgNO3==CsNO3+AgI↓, ko AgI (he iodide hiriwa) he totoka kowhai e kore e rewa ki te wai.
