Mastering Ionic Equations Through Chemical Reactions

The video tutorial explains how to create total and net ionic equations. It begins with the need for a balanced chemical equation and demonstrates the process using calcium nitrate and phosphoric acid. The tutorial covers the steps to balance the equation, break down aqueous compounds into ions for the total ionic equation, and identify spectator ions to form the net ionic equation. The importance of solubility rules and the role of spectator ions are highlighted. The tutorial concludes with a recap of the steps involved in creating ionic equations.

What is the first step in creating total and net ionic equations?

• Calculate the molar mass of reactants

• Identify spectator ions

• Write a balanced chemical equation

• Determine the solubility of compounds

In a double displacement reaction, what happens to the ions?

• They form a gas

• They exchange partners

• They remain unchanged

• They dissolve in water

Which of the following compounds is likely to precipitate in a solution?

• Potassium nitrate

• Calcium phosphate

• Ammonium sulfate

• Sodium chloride

What is the purpose of breaking down aqueous compounds into ions?

• To increase the reaction rate

• To identify the limiting reactant

• To create a total ionic equation

• To measure the pH of the solution

How many nitrate ions are present in the total ionic equation for the reaction discussed?

• 9

• 12

• 6

• 3

What are spectator ions?

• Ions that do not change during the reaction

• Ions that are only present in solid form

• Ions that participate in forming a precipitate

• Ions that increase the solubility of compounds

Which ions are removed to form the net ionic equation?

• Ions that are gaseous

• Ions that form a solid

• Ions that are only on the left side

• Ions that are aqueous on both sides

What is the net ionic equation for the reaction between calcium ions and phosphate ions?

• Ca2+ + NO3- → Ca(NO3)2

• Na+ + Cl- → NaCl

• Ca2+ + PO43- → Ca3(PO4)2

• H+ + OH- → H2O

Why is it important to know solubility rules when writing ionic equations?

• To predict the color of the solution

• To measure the temperature change

• To determine which compounds will precipitate

• To calculate the reaction rate

What is the final step in creating a net ionic equation?

• Measuring the pH

• Balancing the equation

• Identifying the limiting reactant

• Crossing out spectator ions
