The net reaction turns out to be balanced for mass and charge, so it's the balanced net ionic equation.

","description":"

Because spectator ions don't actually participate in the chemistry of a reaction, you don't always need to include them in a chemical equation. A redox reaction is described by the equation: Mg (s) + CuSO (aq) MgSO (aq) + Cu (s). Since its a solid, we dont have These ions just "spectate" (watch) while the other ions form the copper chloride. There are different types of ions, including cations, anions, and spectator ions. Learn more about our Privacy Policy. In the representation of a chemical reaction, the net ionic equation always shields the existence of the spectator ions, although it has been involved in the initial reaction.Hence, the total ionic reaction always exists as different from the net reaction. Answer (1 of 3): Let's use the following reaction: HCl(aq) + Na(OH)(aq) -> H2O(l) +NaCl(aq) Now, we know that all of the aqueous substances are disassociated so we . This should be carried out on either the printable sheet (in this booklet) or on the integrated instruction sheet.
