If lead is dissolved in nitric acid and then allowed to react with potassium iodide, an insoluble lead iodide compound is formed the mass of iodide in the lead iodide compound can be calculated by deducting the initial mass of lead from the mass of the precipitate. There are two general situations in which qualitative analysis is used - in the identification of a simple salt, or the identification of multiple cations in a solution the addition of chromate ion to this lead acetate solution yields a precipitate of yellow lead chromate pb 2+ (aq) + so 4 2-(aq) → pbso 4 (s) bromide and iodide are. 1 answer to you made 1000 ml of a lead(ii) nitrate solution for lab but forgot to cap it the next lab session you noticed that there was only 800 ml left (the rest had evaporated) in addition, you forgot the initial concentration of the solution. The solubility between alkaline earth metals and lead with iodide are different because all of the alkaline earth metals are soluble but lead is not soluble and formed a bright yellow precipitate related essays.

Essay writing guide learn the art of brilliant essay writing with help from our teachers lead iodide precipitate lab report what mole ratio of lead chloride and sodium iodide results in then greatest amount of lead iodide as a precipitate hypothesis: if i mix 2 ml of lead chloride and 3 ml of sodium iodide, then i will get the. Lab report: the formula of lead (ii) iodide 1 attached 2 attached 3 the ratio that yielded the greatest amount of precipitate was 1:2 this means that the experimentally determined ratio of lead ions to iodide ions in lead (ii) iodide is 1:2. Alexander nguyen-huynh purpose: in this lab, you’ll be seeing the reaction of lead (ii) nitrate with potassium iodide to form a lead (ii) iodide precipitate and aqueous potassium nitrate materials: 75 ml graduated cylinder 250 ml beaker 08 grams potassium iodide 10 grams lead (ii) nitrate glass stirring rod filter paper glass funnel. Read this essay on lab report come browse our large digital warehouse of free sample essays (like when reacting zinc and iodine, zinc iodide and excess zinc was produced) also, while heating our zinc iodide for this lab, near the end we made sure none of the product spilled out of the tube their centrifuged product also produced a.
Complex formation and precipitation introduction precipitation is the formation of a solid in a solution as the result of either a chemical reaction, or supersaturating a solution with a salt resulting in solid material collecting on the bottom of the beaker (housecroft & constable, 2006. Example: lead nitrate and potassium iodide place a “p” in the box if you expect a precipitate to form and “nr” if you do not think a reaction will occur consider solutions listed in the first row of the table in question 1 of your lab report for example, the first test. The three major requirements for a good gravimetric analysis are that (a) the reagent will react only with the analyte of interest to form a precipitate, (b) it forms one and only one product with the analyte and (c) that the analyte precipitates quantitatively from solution, that is, 9999. Development of an equation maggie purpose: investigate a chemical reaction using lab procedures and observations then, find a pattern of reactivity and explain the findings using a chemical equation and particle diagram.
