Spectator ions are ions present in a reaction but do not take part in it, remaining unchanged throughout the process. For example: MgCl2 + NaOH → Mg(OH)2 + NaCl is balanced to get MgCl2 + 2NaOH → Mg(OH)2 + 2NaCl. When strong acids dissociate, they dissociate completely, so an anion of a strong acid would not react with any of the ions in the solution, because it would not want to reform the strong acid. Calculators. To identify a spectator ion, write out the complete ionic equation and then cross out the ions that appear on both sides of the equation. The \(\ce{Na^{+}}\) ions are spectator ions, so they can be ignored in the equilibrium equation. Следуя предоставленным Cum se utilizează Spectator Ion Calculator.
