Net Ionic Equations Single Replacement Date:

General Guidelines Net ionic equations for SR rxn follow the same procedures as NI DR, but only ONE ion gets canceled.

Example 2 NaI + Br 2 2 NaBr + I 2 Fill in state of matter using solubility chart and PT. This is the MOLECULAR EQUATION Rewrite aqueous compounds as ions

2Na + (aq) + 2I - (aq) + Br 2(l) 2Na + (aq) + 2Br - (aq) + I 2(s) This is the COMPLETE IONIC EQUATION Cancel the matching ion from both sides.

2I - (aq) + Br 2(l) 2Br - (aq) + I 2(s) This is the net ionic equation.

Aqueous lithium chloride reacts with fluorine gas. 2Cl - (aq) + F 2(g) Cl 2(g) + 2F - (aq)

Aqueous magnesium bromide reacts with lithium. Mg +2 (aq) + 2Li (s) Mg (s) + 2Li + (aq)

Hints There MUST be one ion on each side of the equation. The charges on both sides of the equation must be equal. Diatomics are ONLY diatomic when they were alone in the original equation – if they come out of a compound they are ions, not diatomic.

Oxidation Reduction When something is oxidized, its charge goes up. When something is reduced, its charge goes down. NI equations make it easy to determine what was oxidized and what was reduced.

Determine Oxidized and Reduced 2I - (aq) + Br 2(l) 2Br - (aq) + I 2(s) 2Cl - (aq) + F 2(g) Cl 2(g) + 2F - (aq) Mg +2 (aq) + 2Li (s) Mg (s) + 2Li + (aq)
