Net Ionic Equations and Spectator Ions

The video tutorial explains how to write the net ionic equation for the reaction between nickel carbonate and hydroiodic acid. It begins with balancing the molecular equation, then determining the states of the substances involved. The tutorial proceeds to split strong electrolytes into ions for the complete ionic equation, identifies and removes spectator ions, and finally writes the net ionic equation. The video concludes by ensuring that both charge and atom counts are balanced in the final equation.

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

• They change state during the reaction

• They remain unchanged and are not included in the net ionic equation

Which ions are considered spectator ions in the reaction between nickel carbonate and hydroiodic acid?

• Iodide ions

• Carbonate ions

• Nickel ions

• Hydrogen ions

What must be ensured when finalizing the net ionic equation?

• The equation is balanced in terms of charge only
