Reinforce the concept that soluble ionic salts are strong electrolytes and the ions are mobile ions in solution, i.e. Lead II nitrate solution plus sodium iodide solution combines to form lead II iodide and sodium nitrate. The Complete ionic equation shows all the ions present in solution separately. The solubility rules tell us that salts of group 1 (IA) metals are soluble, salts containing the nitrate anion are soluble, and salts containing the iodide anion are insoluble except for those containing the lead(II) cation (among others).

Both lead nitrate and potassium iodide are very poisonous. 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. the ions are mobile, until they find each other and form a solid. Chemical bond A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. A common threshold to describe something as insoluble is less than 0.1 g per 100 mL of solvent. In the complete ionic equation, soluble ionic compounds and strong acids are rewritten as dissociated ions. This demonstration, with the pedagogy of having students "do the work" of predicting products, writing equations, and drawing particle level diagrams works best if it is presented AFTER the precipitation of silver chromate demonstration - which is done in a teacher directed manner.
