Net Ionic Equations and Their Components

The video tutorial explains how to write a balanced net ionic equation for the reaction between sodium hydroxide and ammonium phosphate. It begins with balancing the molecular equation, then assigns states to each substance. The tutorial proceeds to split strong electrolytes into ions for the complete ionic equation, identifies and removes spectator ions, and finally balances charges to finalize the net ionic equation.

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

• Balance the molecular equation

• Identify spectator ions

• Split strong electrolytes into ions

• Write the states of substances

What state is sodium hydroxide in during the reaction?

• Gas

• Solid

• Aqueous

• Liquid

Why are ammonium compounds considered aqueous?

• They remain as solids

• They are strong acids

• They dissolve and dissociate into ions

• They are weak bases

Why is it important to write the states of substances in a reaction?

• To calculate the reaction speed

• To understand how substances interact

• To determine the temperature of the reaction

• To identify the color of substances

Which substances are not split into ions in the complete ionic equation?

• Strong bases

• Aqueous solutions

• Weak bases and gases

• Strong acids

What is the role of spectator ions in a net ionic equation?

• They change the charge balance

• They form new compounds

• They are removed from the equation

• They participate in the reaction

How do you ensure the net ionic equation is balanced?

• By balancing charge and atoms

• By adding more reactants

• By ensuring equal mass on both sides

• By checking the number of molecules

What happens to the coefficients in the final net ionic equation?

• They are reduced to the simplest form

• They are doubled

• They are removed

• They remain unchanged

What is the net charge on both sides of a balanced net ionic equation?

• Positive

• Varies

• Negative

• Zero

What is the significance of the positive ion being placed first in the net ionic equation?

• It affects the reaction rate

• It is a convention for clarity

• It changes the reaction outcome

• It is required for balancing
