Short answer

Question: Write the balanced net ionic equation for each reaction of the given aqueous solutions with H+ ions: a) Sodium sulfite b) Lithium hydroxide c) Potassium benzoate Answer: a) SO3²⁻ (aq) + 2H+ (aq) → H2O (l) + SO2 (g) b) OH⁻ (aq) + H+ (aq) → H2O (l) c) C7H5O2⁻ (aq) + H+ (aq) → C7H6O2 (aq)

Step-by-step solution

Write the chemical equation

The reaction between sodium sulfite (Na2SO3) and H+ ions (from an acid) can be represented as: Na2SO3 (aq) + 2H+ (aq) → 2Na+ (aq) + H2O (l) + SO2 (g) #Step 2: Identify the spectator ions#

Spectator ions identification

Spectator ions are the ions in the equation that do not undergo any change during the reaction. In this case, Na+ ions are the spectator ions as they appear on both sides of the equation without any change. #Step 3: Write the balanced net ionic equation#

Balanced net ionic equation

The net ionic equation can be obtained by removing the spectator ions. SO3^{2-} (aq) + 2H+ (aq) → H2O (l) + SO2 (g) #b) Lithium hydroxide reacting with H+ ions# #Step 1: Write the chemical equation#

Write the chemical equation

The reaction between lithium hydroxide (LiOH) and H+ ions (from an acid) can be represented as: LiOH (aq) + H+ (aq) → Li+ (aq) + H2O (l) #Step 2: Identify the spectator ions#

Spectator ions identification

Spectator ions are the ions in the equation that do not undergo any change during the reaction. In this case, Li+ ions are the spectator ions as they appear on both sides of the equation without any change. #Step 3: Write the balanced net ionic equation#

Balanced net ionic equation

The net ionic equation can be obtained by removing the spectator ions. OH^{-} (aq) + H+ (aq) → H2O (l) #c) Potassium benzoate reacting with H+ ions# #Step 1: Write the chemical equation#

Write the chemical equation

The reaction between potassium benzoate (KC7H5O2) and H+ ions (from an acid) can be represented as: KC7H5O2 (aq) + H+ (aq) → K+ (aq) + C7H6O2 (aq) #Step 2: Identify the spectator ions#

Spectator ions identification

Spectator ions are the ions in the equation that do not undergo any change during the reaction. In this case, K+ ions are the spectator ions as they appear on both sides of the equation without any change. #Step 3: Write the balanced net ionic equation#

Balanced net ionic equation

The net ionic equation can be obtained by removing the spectator ions. C7H5O2^- (aq) + H+ (aq) → C7H6O2 (aq)
