The correct Answer is:
To determine why sodium carbonate is classified as a basic salt, we can follow these steps: ### Step 1: Identify the Components of Sodium Carbonate Sodium carbonate (Na2CO3) is formed from sodium ions (Na+) and carbonate ions (CO3^2-). ### Step 2: Determine the Nature of the Acid and Base Sodium carbonate is produced from the reaction of a strong base and a weak acid. Specifically, it is formed from sodium hydroxide (NaOH), which is a strong base, and carbonic acid (H2CO3), which is a weak acid. ### Step 3: Analyze the Properties of the Salt When a salt is formed from a strong base and a weak acid, the resulting salt tends to be basic in nature. This is because the weak acid does not completely dissociate in solution, leaving an excess of hydroxide ions (OH-) from the strong base. ### Step 4: Conclusion Since sodium carbonate is derived from a strong base (NaOH) and a weak acid (H2CO3), it is classified as a basic salt. ### Final Answer Sodium carbonate is a basic salt because it is a salt of a weak acid (carbonic acid) and a strong base (sodium hydroxide). ---
