Notice that there are ions that are present on both sides of the reaction arrow –> that is, they do not react. These ions are known as spectator ions and they are eliminated from complete ionic equation by crossing them out. The remaining equation is known as the net ionic equation. For example: The reaction of potassium chloride and lead II ...
Our answer, 0.233 g Mg(OH)2, is reasonable. The Moles of Ions before Reaction final concentrations of the spectator ions are lower than the initial concentrations, so that makes Mg2+ 7.50 × 10-3 mol Cl- 15.0 × 10-3 mol sense, too, because of the dilution effect. 8.00 × 10-3 mol OH- 8.00 × 10-3 mol Na+ 0 . 0250 L MgCl 2 soln × 1 . 00 L MgCl ...
Not all species in the equation for a chemical reaction are involved in producing an insoluble compound, a gas or water. Spectator ions are the ions that aren't involved in the chemical reaction.

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. Spectator Ions. We also have the potential to have some ions in solution that do not participate in the chemistry. This is because these ions are the conjugate pairs for the strong acids or strong bases. Since those reactions are assumed to go 100% in the forward direction, we can likewise assume they go backwards 0%.
