Key Difference – Balanced Equation vs Net Ionic Equation All chemical reactions can be written as an equation. Net Ionic Equation Calculator To write a net ionic equation you have to write the balanced molecular equation. For example, in the reaction between silver nitrate (AgNO3) and sodium chloride (NaCl) in water, the complete ionic equation is: Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) → AgCl(s) + Na+(aq) + NO3-(aq). Additionally, the net charge is the same on both sides of the equation. The overall chemical equation shows all the substances present in their undissociated forms; the complete ionic equation shows all the substances present in the form in which they actually exist in solution; and the net ionic equation is derived from the complete ionic equation by omitting all spectator ions, ions that occur on both sides of the equation with the same coefficients. The net ionic equation is a chemical equation for a reaction that lists only those species participating in the reaction. Cross out the spectator ions on both sides of complete ionic equation. NOTE: gases, solids, and liquids DO NOT dissociate and remain in their molecular forms! Usually, this is a salt dissolved in water, where the ionic species are followed by (aq) in the equation to indicate they are in aqueous solution. ? Notice that the phosphoric acid was written in a molecular way. When the two solutions are mixed, neither the Na + nor the NO 3 − ions participate in the reaction.

Identify all of the phases in your answer. • This worksheet will help you practise writing ionic equations for neutralisation and precipitation reactions • Where state symbols are not given, you’ll need to use the solubility rules to determine whether a substance will ionise Write ionic equations for the following: 1. The net ionic equation cancels out ions that appear on both sides of the reaction arrow because they essentially don't participate in the reaction of interest. Helmenstine, Anne Marie, Ph.D. "What Is an Ionic Equation and How Is It Used?" AP® is a registered trademark of the College Board, which has not reviewed this resource. The ions that are canceled out are called spectator ions. The ions in aqueous solutions are stabilized by ion-dipole interactions with water molecules. Ionic equations are used for single and double displacement reactions that occur in aqueous solutions. The sodium cations and the chloride anions act as spectator ions because they are present on both sides of the chemical equation as ions. All of them are technically correct, but each one is meant to show a different thing. HCl (aq) HNO 3(aq) + NaOH (aq) → NaNO 3(aq) + H 2 O (l) 2. The complete ionic equation is the entire chemical equation with all aqueous substances dissociated into their respective ions. Strong acids, strong bases, and soluble ionic compounds (usually salts) exist as dissociated ions in aqueous solution, so they are written as ions in the ionic equation.
