Balancing Net Ionic Equations

The video tutorial explains how to balance a net ionic equation for hydrochloric acid and mercury(I) nitrate. It begins with balancing the molecular equation, identifying the states of substances using solubility rules, and forming the complete ionic equation. The tutorial highlights the importance of not splitting solids and keeping certain ions together. It concludes with identifying spectator ions, forming the net ionic equation, and ensuring that charges and atoms are balanced.

What is the first step in balancing a net ionic equation?

• Identify spectator ions

• Balance the molecular equation

• Determine the states of substances

• Split strong electrolytes into ions

How do you balance the number of chlorine atoms in the molecular equation?
