golden rain demonstration is made by combining two colorless solutions, potassium iodide solution and lead(ii) nitrate solution at room temperature to form yellow precipitate. during the chemical reaction, golden particles gently drop from the top of erlenmeyer flask to bottom, similar to watching the rain through a window. the golden rain chemical reaction demonstrates the formation of a solid precipitate. the golden rain experiment involves two soluble ionic compounds, potassium iodide (ki) and lead(ii) nitrate (pb(no)). they are initially dissolved in separate water solutions, which are each colorless. when mixed, as the lead from one solution and the iodide from the other combine to form lead(ii) iodide (pbi), which is insoluble at low temperature and has a golden bright yellow color. although this is a reaction solely of the dissociated ions in solution, it is sometimes written as a double displacement reaction:

products are the species formed from chemical reactions. during a chemical reaction reactants are transformed into products after passing through a high energy transition state. this process results in the consumption of the reactants. it can be a spontaneous reaction or mediated by catalysts which lower the energy of the transition state, and by solvents which provide the chemical environment necessary for the reaction to take place. when represented in chemical equations products are by convention drawn on the right-hand side, even in the case of reversible reactions. the properties of products such as their energies help determine several characteristics of a chemical reaction such as whether the reaction is exergonic or endergonic. additionally the properties of a product can make it easier to extract and purify following a chemical reaction, especially if the product has a different state of matter than the reactants. reactants are molecular materials used to create chemical reactions. the atoms aren't created or destroyed. the materials are reactive and reactants are rearranging during a chemical reaction. here is an example of reactants: ch + o. a non-example is co + ho or "energy".
