Putting sodium iodide in a toilet and hydrogen peroxide in the tank?I?
Q. I want to do this to some of the school toilets on the last day of school (students leaving always play pranks on the last day). I've heard hydrogen peroxide can be quite dangerous, would it still be if mixed with sodium iodide? and also where could i get hold of some of these chemicals, and can anyone tell me about how much of each i would need? I don't do chemistry that's why I'm asking. Plus I do fine in school it would just be fun to cause a little chaos for one day.

A. I think you should pay more attention in school, particularly chemistry class, and stop thinking of ways to cause problems. for instance hydrogen peroxide (H2O2) isn't particularly dagerious in fact you can buy it at any pharmacy without any restrictions.

A. 2NaI + Cl2 ==> 2NaCl + I2 0.29g NaI x (1 mol NaI / 149.9g NaI) = 0.00194 mol NaI 0.00194 mol MaI x (2 mol NaCl / 2 mol NaCl) = 0.00149 mol NaCl 0.00149 mol NaCl x (58.5g NaCl / 1 mol NaCl) = 0.113g NaCl

Help! Does allyl bromide react well in a solution of sodium iodide in anhydrous acetone?
Q. I know that this if these do react, that it's an SN2 reaction. Also wondering what is unusual about an allyl in this reaction. Thank you!

A. The reaction is much faster then that for bromopropane due to stabilization of the positive character of the carbon in the transition state by pi electron donation from the double bond.

Why do Sucrose and Isopropyl Alcohol not conduct electricity, while Sodium Iodide conducts electricity?
Q. Hi guys. I just had a Chemistry Lab today about Ionic, Covalent and Metallic bonds, and how their compounds react to electricity. Well, I'm still puzzled about why Sucrose and Isopropyl Alcohol don't conduct electricity, while Sodium Iodide conducts electricity strongly? Any help guys? Thank you :)

A. Sucrose and alcohol are molecular compounds whereas Sodium Iodide is an ionic compound. Ionic compounds are electrolytes (can't remember if they're strong or weak though), but they conduct electricity. Hence, sodium iodide conducts electricity while sucrose and isopropyl alcohol don't

A. to test positive for Fe+2 ions, you need to you find a reactant that will precipitate the iron in solution. for example sodium phosphate, the sodium will remain as an ion and the phosphate will too, however, phosphate ions PO4-3 will react with iron to form iron(II) phosphate which is an insoluble rocky llight yellow/brownish colored salt.

Asked by Martin C - Sun Oct 14 20:40:36 2007 - - 2 Answers - 0 Comments

A. Table salt is also often iodized a small amount of potassium iodide (in the US) or potassium iodate (in the EU) is added as an important dietary supplement. Potassium iodide is added as a nutrient, to prevent goiter, a thyroid gland problem caused by lack of iodine, and to prevent mental retardation associated with iodine deficiency. A project started by the Michigan State Medical Society in 1924 promoted the addition of iodine to table salt, and by the mid 1950's, three quarters of U.S. households used only iodized salt. Potassium iodide makes up 0.06% to 0.01% of table salt by weight. Sometimes cuprous iodide (iodide of copper) is used as the source of iodine. Iodized table salt has significantly reduced disorders of iodine deficiency… [cont.]

A. Sodium iodide is an ionic compound, any water in the experiment will cause the NaI to dissolve into Na+ and I- and plus give you a false result.

Q. How many grams of sodium nitrate can be formed?
Asked by Jay - Mon Jun 1 03:55:53 2009 - - 2 Answers - 0 Comments

A. 1. Pb(NO3)2 + 2NaI --> 2NaNO3 + PbI2 2. Work out the moles of lead (II) nitrate and sodium iodide. n = mass / Mr n = 25 / 331.2 = 0.0755 Mol of Pb(NO3)2 n = 15 / 150 = 0.1 Mol of NaI 3.Find ratio between Pb(NO3)2 and NaI to workout the limiting reagent 1: 2 (need to divide the 2 to make it constant with the 1) 0.0755 : 0.1/2 0.0755 : 0.05 Therefore, the limiting reagent is NaI. 4. n(NaI)/2 : n(NaNO3)/2 0.1/2 : n(NaNO3)/2 0.1 : n(NaNO3) m = n x Mr m = 0.1 x 85 = 8.5 grams of NaNO3. Check my calculations if they're wrong. Hope that helped. My Apologises I made a stupid error...fixed it now
