Answer to analysis of the lead/lead(ii) iodide concentration cell: write the overall reaction equation, indicating which species w. Lead would have an oxidation state of 2+ because iodide has a charge of 1- and in the formula there are two iodides for one lead so 2(-1) is a -2 oxidation number so to neutralize the formula lead has to has a charge of 2+. How do you write the the reaction of lead(ii) nitrate (aq) with sodium iodide (aq) to form lead (ii) iodide precipitate and sodium nitrate solution. Precipitation of lead(ii) iodide when a few crystals of lead nitrate and potassium iodide are added to opposite sides of a petri dish containing deionized water, after a few minutes, a line of bright yellow lead(ii) iodide precipitate forms down the middle of the dish.
