2 Al(NO₃)₃ (aq) + 3 Na₂S (aq) → Al₂S₃ (s) + 6 NaNO₃ (aq)
Here's a breakdown of the reaction:
* Reactants:
* Aluminum nitrate (Al(NO₃)₃): A colorless, soluble salt.
* Sodium sulfide (Na₂S): A colorless, soluble salt.
* Products:
* Aluminum sulfide (Al₂S₃): A white, insoluble precipitate.
* Sodium nitrate (NaNO₃): A colorless, soluble salt.
Explanation of Balancing:
* Aluminum (Al): We need 2 aluminum atoms on both sides.
* Nitrate (NO₃): We need 6 nitrate ions on both sides.
* Sodium (Na): We need 6 sodium ions on both sides.
* Sulfide (S): We need 3 sulfide ions on both sides.
Important Note: This reaction produces a precipitate, aluminum sulfide. This indicates a double displacement reaction, where the cations and anions of the reactants switch partners.
