Arrange some questions about Sodium iodide (NaI) for you Sodium iodide (NaI), guidechem, 7681-82-5 Q1:How to describe the formation of an ionic bond in sodium iodide? A1:Sodium Iodide : NaI CAS NO: 7681-82-5 Sodium has 1 electron in its outermost shell. It is easier to lose 1 electron then to gain 7 electrons in order to complete is octet. Iodine has 7 electrons in its outermost shell. It is easier to gain 1 electron then to lose 7 electrons in order to complete is octet. So sodium donates its electron to Iodine and complete's its octet and Iodine accepts the electron to complete its octet. This forms a bond between them which is known as an ionic/electrovalent bond. Q2: Silver nitrate or Sodium iodine? Explanation: I have come to you for some advice about Silver Nitrate or Sodium iodine because today I was doing an experiment in class and i was experimenting with Silver nitrate and Sodium iodine and I accidently got one of the chemicals on to my fingers and now my fingers have stained brown and I can't wash it up with regular soap and water so what shall I do? A2:Silver nitrate gets under your skin. You probably didn't notice it until after you were out in the sunlight, I'm guessing, that's because silver ions react with water in the presence of light to form silver oxide - this reaction was once used in black and white photography. It looks brown at first because it just darkens your natural skin tone. If you got enough of it on your skin, then as it gets exposed to more light it may even turn close to black. But regardless, it's actually IN your skin now, and you can't get it back out. So choose Sodium iodine. Q3:What forms a precipitate with Sodium Iodide (NaI)? A3:If you added AgNO3, silver nitrate, the silver formes a precipitate with any halide, and the NaNO3 would rremain in the water, as all alkalai metals do. Q4: What may happen, when we mix Sodium iodide(CAS NO;7681-82-5) into water? A4:Firstly, Sodium iodide will dissolve in water. To determine if it is a physical change, can you recover NaI when the water is evaporated? Is changing water to steam a physical change? Is changing steam to water a physical change?
