Net Ionic Equations and Reactions

The video tutorial explains how to write a balanced net ionic equation for the reaction between sodium iodide and lead(II) nitrate. It begins by balancing the molecular equation, then determines the solubility and states of the compounds involved. The tutorial proceeds to split the compounds into ions to form the complete ionic equation, and finally derives the net ionic equation by removing spectator ions. The video concludes by ensuring charge and atom balance in the equation.

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

• Identify spectator ions

• Balance the molecular equation

• Determine the solubility of compounds

• Split compounds into ions

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

• They are always soluble

• They form gases

• They are often insoluble

• They react with water

What does 'ss' indicate on a solubility chart?

• Solid state

• Saturated solution

• Strongly soluble

• Slightly soluble

What charge does a sodium ion typically have?

• 2-

• 1-

• 1+

• 2+

Why don't we split solids in net ionic equations?

• They do not dissociate into ions

• They are already balanced

• They are insoluble

• They are not reactive

What is the role of spectator ions in a reaction?

• They form the main product

• They do not participate in the reaction

• They change the state of the reaction

• They participate in the reaction

What is conserved in a balanced net ionic equation?

• Charge only

• Mass only

• Neither mass nor charge

• Both mass and charge

Why is it common to place the positive ion first in net ionic equations?

• It is a convention for clarity

• It balances the equation

• It changes the reaction

• It affects solubility

What happens to the number of atoms on both sides of a balanced equation?

• They become zero

• They increase

• They decrease

• They remain the same

What is the final product of the reaction between sodium iodide and lead(II) nitrate?

• Sodium chloride

• Lead(II) iodide

• Iodine gas

• Sodium nitrate
