Question

1. Use structural formulas to depict balanced acid-base reactions (net ionic equation) of the solid aspirin product with HCO3-. Include (aq), (l), (g) phase subscripts.

2. Use structural formulas to depict balanced acid-base reactions (net ionic equation) of the aspirin sodium salt anion with H+. Include all (s) and (aq) phase subscripts.

3. Why do you think the aspirin was wished with distilled water? How does it affect the end product? the actual product yield?

Answer 1

Answer 1):-

This is an acid-base reaction. Aspirin (Acetyl salicylic acid) reacts with the bicarbonate anion (base) to form acetyl salicylate, water and carbon dioxide.The balanced chemical equation ( net-ionic equation) can be given as:

--------------------------------------------------------------

Answer 2):-

This is acid-base type reaction. Sodium acetyl salicylate (base) reacts with H⁺ (acid) to form aspirin (acetyl salicylic acid). The balanced chemical equation (net-ionic equation) can be given as:

-------------------------------------------------------------

Answer 3):-

Aspirin is washed with distilled water to remove the water-soluble impurities. This give a better yield of the product.
