Is NO3 a spectator ion? Necessary cookies are absolutely essential for the website to function properly. Step 1 :Consider the complete ionic equation in which sodium chloride reacts with copper sulfate. The states can be removed while entering the chemical equation. In the net chemical reaction, the spectator ions are cancelled from both sides of the equation. In cases where the spectator ion has no function on its own, this simplified equation can be used without losing significant information about the reaction. Write the net ionic equation when aqueous solutions of copper(II) chloride and potassium phosphate are mixed, a precipitate of copper(II) phosphate is formed. Since a spectator ion doesnt The term net ionic indicates that the electric charge on both sides of the equation needs to be balanced and equal. Use simple laboratory tests to identify the following ions in solution: CO32-, SO42-, Cl-, I . Therefore, they are termed as spectator ions. The spectator ions are canceled out of a reaction when writing the net ionic equation, so the net ionic equation for this example would be: Although spectator ions are ignored in the net reaction, they affect the Debye length.
