Net Ionic Equations and Reactions

The video tutorial explains how to write a balanced net ionic equation for a reaction involving zinc and copper(II) nitrate. It begins by ensuring the molecular equation is balanced and checks the reaction's feasibility using the activity series. The states of each substance are determined, and strong electrolytes are split into ions to form the complete ionic equation. Spectator ions are then removed to derive the net ionic equation.

What is the first step in writing a balanced net ionic equation?

• Balance the molecular equation

• Check the solubility of the reactants

• Identify spectator ions

• Determine the products of the reaction

Why is it important to check the activity series in a single displacement reaction?

• To determine the solubility of the products

• To identify the spectator ions

• To ensure the reaction is balanced

• To verify if the reaction will occur
