What is the word equation for the precipitation of lead iodide?

Lead iodide precipitate can be produced by reacting potassium iodide ( ) with lead II nitrate ( ). The chemical equation for this reaction is:


    + -> +


This is a double replacement reaction that results in the formation of a precipitate. This type of reaction can also be called a precipitation reaction. 


The solubility of a substance can be determined by looking at a list of solubility rules. A list of solubility rules can be found in your textbook or online. The solubility rules tell us that is insoluble and will form a solid precipitate. 


Therefore, the word equation for this reaction would be:


Aqueous potassium iodide reacts with aqueous lead II nitrate to produce solid lead II iodide and aqueous potassium nitrate.
