When ethanoic acid (also known as acetic acid) is added to solid sodium bicarbonate (also known as baking soda), the following observations would be observed:
Brisk effervescence
- The addition of ethanoic acid to solid sodium bicarbonate leads to a chemical reaction known as an acid-base reaction or neutralization reaction. In this reaction, ethanoic acid (CH3COOH) donates a hydrogen ion (H+) to the bicarbonate ion (HCO3-) in sodium bicarbonate (NaHCO3), resulting in the formation of carbon dioxide gas (CO2), water (H2O), and sodium acetate (CH3COONa).
- The production of carbon dioxide gas during the reaction is what causes the brisk effervescence or bubbling to occur. Carbon dioxide gas is a colorless and odorless gas that is released as bubbles when the reaction takes place.
- The effervescence can be visually observed as bubbles forming and rising to the surface of the solution. It is a rapid and vigorous process, giving the appearance of fizzing or bubbling.
- The release of carbon dioxide gas is the reason behind the bubbles forming, as the gas escapes from the solution. This effervescence is similar to what happens when baking soda is mixed with vinegar, as vinegar contains acetic acid.
- It is important to note that ethanoic acid is a weak acid, so the reaction is not as vigorous as with stronger acids, but it still produces a noticeable effervescence.
- Therefore, the correct observation when a few drops of ethanoic acid are added to solid sodium bicarbonate is brisk effervescence.
In summary, the addition of ethanoic acid to solid sodium bicarbonate results in a brisk effervescence due to the production of carbon dioxide gas. The gas bubbles escape from the solution, causing the observed bubbling or fizzing.
