The ionic equations are; ZnCl 2----- > Zn +2 + 2Cl-1 Pb(NO 3) 2----- > Pb +2 + 2NO 3-1 The net ionic equation for the reaction is; The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration, where adding more solute does not increase the concentration of the solution and begins to precipitate the excess amount of solute. PbI2 (lead iodine), however, is ionic. while the demo proceeds. 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. Lead nitrate is also a strong oxidizing agent. The solubility of a substance is an entirely different property from the rate of solution, which is how fast it dissolves. In a large lecture hall a document camera is necessary to project the image of the reaction. The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and the pH of the solution.

A common threshold to describe something as insoluble is less than 0.1 g per 100 mL of solvent. This demonstration, when presented as a guided-inquiry active student learning approach, combined with particle diagrams can be highly effective because it addresses all three areas of Johnstone's triangle: macroscopic, symbolic, and microscopic (particle level). The name of the metal is written first, followed by the name of the nonmetal with its ending changed to – ide . Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound. To transform a complete molecular equation to a complete ionic equation, you need to know the difference between an ionic compound and a molecular compound. 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 I-ions must migrate in the aqueous solution, i.e. When combined with computer animations of the dissolving process and the migration of ions to form lead(II) iodide (macroscopic level) this demonstration is an effective teaching tool.
