Net Ionic Equations and Solubility

The video tutorial explains how to write a net ionic equation for the reaction between lead(II) nitrate and sodium chloride. It covers balancing the molecular equation, determining the states of compounds using solubility rules, splitting strong electrolytes into ions, and identifying spectator ions to derive the net ionic equation. The tutorial concludes with a summary of the steps and the final net ionic equation.

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

• Identify spectator ions

• Balance the molecular equation

• Split compounds into ions

• Determine the states of the compounds

Why is it important to know the solubility of lead compounds?

• Their solubility varies and affects the state in the equation

• They are always soluble

• They do not participate in reactions

• They are always insoluble

What does 'SS' indicate in a solubility table?

• Strongly soluble

• Slightly soluble

• Solid state

• Sodium sulfate

Which ions are not split into their components in net ionic equations?

• Solid, liquid, or gas compounds

• All ions

• Aqueous ions

• Only gaseous compounds

What is the charge of a nitrate ion?

• 2+

• 1-

• 2-

• 1+

What is the purpose of identifying spectator ions?

• To balance the equation

• To simplify the net ionic equation

• To determine solubility

• To find the molecular weight

Which ions are considered spectator ions in this reaction?

• Lead and chloride ions

• Sodium and nitrate ions

• Chloride and nitrate ions

• Lead and sodium ions

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

• Determining solubility

• Identifying spectator ions

• Adding the states of the compounds

• Balancing the charges

What is the net ionic equation for the reaction between Pb(NO3)2 and NaCl?

• 2Na^+ + 2Cl^- → 2NaCl
