Net Ionic Equations

Net Ionic Equations • Net ionic equations are used to show which ions participate in the reaction. • Ions that do NOT participate in the reaction are spectator ions.

Net Ionic Equations Overall equation: Ag. NO 3 (aq) + Na. Cl (aq) → Ag. Cl (s) + Na. NO 3 (aq) • Separate all of the ions: Compounds that are soluble (AKA - aq) will separate into their ions. Precipitates (AKA - s) DO NOT separate. Ag+(aq) + NO 3 -(aq) + Na+(aq) + Cl-(aq) → Ag. Cl(s) + Na+(aq) + NO 3(aq) • Cross out all spectator ions - the ions that appear on both the reactant and product side of the equation.

Net Ionic Equations Ag+(aq) + NO 3 -(aq) + Na+(aq) + Cl-(aq) → Ag. Cl(s) + Na+(aq) + NO 3(aq) • What remains is the net ionic equation: Ag+(aq) + Cl-(aq) → Ag. Cl (s) • Balancing Net Ionic Equations: must be balanced with respect to both coefficients and charge

Fe. Cl 3 (aq) + KOH (aq) → a. Predict the products of the following reaction. b. Write the FULL ionic equation. (Yes - the long one) c. Write the NET IONIC EQUATION. d. What are the spectator ions.

ANSWERS Fe. Cl 3 (aq) + KOH (aq) → a. Predict the products of the following reaction. Fe (OH )3+ KCl b. Write the FULL ionic equation. (Yes - the long one) Fe. Cl 3 (aq) + KOH (aq) → Fe (OH)3 (s) + KCL (aq) NOW… BALANCE Fe. Cl 3 + 3 KOH Fe(OH)3 + 3 KCL c. Write the NET IONIC EQUATION. Fe+3 (aq) + Cl-1 (aq) + 3 K+1 (aq) + 3 OH-1 (aq) -- Fe (OH)3 d. What are the spectator ions. Cl -, K+ +1 -1 + 3 K + 3 Cl (s) (aq)
