Example- Pb(NO 3) 4 write the name "lead nitrate". Since lead has more than one oxidation state we must figure out which lead we have. Since each nitrate (4 of them) has a 1- charge, the Pb must be 4+. So our roman numeral will be (IV). Pb(NO 3) 4 is named "lead(IV) nitrate" Highlight to reveal names Sep 18, 2009 · The chemical formula Tin (II) Iodide is SnI2. The chemical formula for Tin (IV) Iodide is SnI4. 1) The formula of sodium iodide is NaI 2) Due to the great electronegativities of sodium (Na) and iodine (I) , sodium iodide is a ionic compound. 3) Ionic compounds dissociate in water to produce the corresponding ions. In this case, since I has the greatest electronegativity, the ions are Na + and I-. Iodide, being large, is less hydrophilic compared to the smaller anions. One consequence of this is that sodium iodide is highly soluble in acetone, whereas sodium chloride is not. The low solubility of silver iodide and lead iodide reflects the covalent character of these metal iodides.
