Answer
This statement is correct. Aspirin (acetylsalicylic acid) has an ester functional group from the acetyl part and retains the carboxylic acid functional group from the salicylic acid.

Answer
This statement is correct. Aspirin can react with sodium bicarbonate (NaHCO₃) as it is acidic, leading to the formation of a salt and carbon dioxide.

Answer
This statement is incorrect. While acetylsalicylic acid can be produced using acetic acid (CH₃COOH), it is not the primary method for synthesizing aspirin as it requires acetic anhydride or acetyl chloride for efficient synthesis.
