Two questions where I have to write a balanced net ionic equation.
1. Write a balanced net ionic equation for the reaction that occurs when aqueous solutions of sodium chromate and silver nitrate are mixed
2. Write a balanced net ionic equaion reaction for the acid-base reaction that takes place between aqueous potassium hydroxide and acetic acid.
For net ionic equations.
1. Write the molecular equation.
2. Separate into ions everything EXCEPT
a. insoluble materials.
b. gases.
c. weak electrolytes.
For everything in 2, write them as the molecule.
Have a try at these and I'll be glad to check them for you.
Sure, I'd be happy to help you write balanced net ionic equations for these reactions!
1. Reaction between sodium chromate and silver nitrate:
Step 1: Identify the soluble ions in the reactants.
- In sodium chromate (Na₂CrO₄), the ions are Na⁺ and CrO₄²⁻.
- In silver nitrate (AgNO₃), the ions are Ag⁺ and NO₃⁻.
Step 2: Determine the possible products of the reaction.
- In this case, the cation Ag⁺ from silver nitrate can combine with the anion CrO₄²⁻ from sodium chromate to form Ag₂CrO₄(s). The other ions Na⁺ and NO₃⁻ do not react.
Step 3: Write the balanced molecular equation.
Na₂CrO₄(aq) + 2AgNO₃(aq) → Ag₂CrO₄(s) + 2NaNO₃(aq)
Step 4: Write the total ionic equation.
2Na⁺(aq) + CrO₄²⁻(aq) + 2Ag⁺(aq) + 2NO₃⁻(aq) → Ag₂CrO₄(s) + 2Na⁺(aq) + 2NO₃⁻(aq)
Step 5: Write the net ionic equation.
CrO₄²⁻(aq) + 2Ag⁺(aq) → Ag₂CrO₄(s)
2. Acid-base reaction between potassium hydroxide and acetic acid:
Step 1: Identify the soluble ions in the reactants.
- In potassium hydroxide (KOH), the ions are K⁺ and OH⁻.
- In acetic acid (CH₃COOH), the ions are H⁺ and CH₃COO⁻.
Step 2: Determine the possible products of the reaction.
- In an acid-base reaction, the OH⁻ from KOH and the H⁺ from acetic acid combine to form water (H₂O). The other ions K⁺ and CH₃COO⁻ do not react.
Step 3: Write the balanced molecular equation.
KOH(aq) + CH₃COOH(aq) → H₂O(l) + CH₃COOK(aq)
Step 4: Write the total ionic equation.
K⁺(aq) + OH⁻(aq) + H⁺(aq) + CH₃COO⁻(aq) → H₂O(l) + CH₃COOK(aq)
Step 5: Write the net ionic equation.
OH⁻(aq) + H⁺(aq) → H₂O(l)
I hope this helps! Let me know if you have any further questions.
1. The balanced net ionic equation for the reaction between sodium chromate (Na2CrO4) and silver nitrate (AgNO3) is:
2 Ag+(aq) + CrO4^2-(aq) → Ag2CrO4(s)
2. The balanced net ionic equation for the acid-base reaction between aqueous potassium hydroxide (KOH) and acetic acid (CH3COOH) is:
CH3COOH(aq) + OH-(aq) → CH3COO-(aq) + H2O(l)
