The only way the solid lead(II) iodide precipitate can form in the middle of the petri dish is for 1) the Pb(NO 3) 2 and the KI to dissociate into ions in the water and 2) the Pb 2 ions and Iions must migrate in the aqueous solution, ie the ions are mobile, until they find each other and form a solid This demonstration provides evidence. Iodide is a form of iodine that carries a slightly different atomic charge and normally is chemically bound with an element of potassium or sodiumWhile many people use the two words interchangeably, that is not exactly correct An iodine atom will not possess the negative one charge that is found with an iodide ionIn addition, there are some applications for iodine that are not suited for.

What Makes A Good Nucleophile?. The iodide ion radius is much larger than the other common halides, which results in the negative charge being dispersed over a large space By contrast, a chloride ion is much smaller, meaning its negative charge is more concentrated, leading to a stronger interaction between the proton and the chloride ion.

An early study of the kinetics of this reaction determined that it “is catalyzed by the iodine product, and the autocatalysis is inhibited by iodide ion” (Kern and Kim 1965, 5309) In 1985. All the absence of a precipitate shows is that you haven't got chloride, bromide or iodide ions present The chemistry of the test The precipitates are the insoluble silver halides silver chloride, silver bromide or silver iodide Silver fluoride is soluble, and so you don't get a precipitate.
