Net Ionic Equations and Solubility

The video tutorial explains how to write a balanced net ionic equation for the reaction between strontium chloride and sodium phosphate. It begins with balancing the molecular equation, followed by determining the states of the compounds using solubility rules. The tutorial then demonstrates how to write the complete ionic equation, identify spectator ions, and finalize the net ionic equation while ensuring charge balance. The process emphasizes the importance of understanding solubility rules and charge neutrality in chemical reactions.

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

• Write the complete ionic equation

• Determine the solubility of compounds

• Balance the molecular equation

• Identify spectator ions

Why are compounds with chloride ions generally soluble?

• They are always in solid form

• They react with sodium ions

• They form strong covalent bonds

• They dissolve easily in water

Which of the following compounds is typically insoluble?

• Sodium chloride

• Potassium phosphate

• Sodium phosphate

• Strontium phosphate

What is the purpose of splitting strong electrolytes into ions?

• To balance the equation

• To identify the precipitate

• To determine solubility

• To write the complete ionic equation

What do you do with spectator ions in a net ionic equation?

• Balance them separately

• Convert them to solids

• Cross them out

• Include them in the final equation

Which ions are considered spectator ions in the reaction between SrCl2 and Na3PO4?

• Strontium and phosphate ions

• Sodium and chloride ions

• Sodium and phosphate ions

• Strontium and chloride ions

What is the net charge of the reactants and products in a balanced net ionic equation?

• Positive

• Depends on the reaction

• Negative

• Zero

How do you ensure the net ionic equation is balanced?

• By balancing the spectator ions

• By balancing both atoms and charges

• By balancing only the charges

• By balancing only the atoms

What is the net ionic equation for the reaction between SrCl2 and Na3PO4?

• Sr^2+ + 2Cl^- + 3Na^+ + PO4^3- → Sr3(PO4)2 + 6Na^+ + 6Cl^-

• Sr^2+ + PO4^3- → Sr3(PO4)2

• 3Sr^2+ + 2PO4^3- → Sr3(PO4)2

• 3Sr^2+ + 6Cl^- + 6Na^+ + 2PO4^3- → Sr3(PO4)2 + 6Na^+ + 6Cl^-
