Phenol as an Acid
- Phenol is a weak acid compared to carbonic acid.
- Phenol has a pKa value of around 9.95, indicating that it is a weaker acid than carbonic acid which has a pKa value of around 6.37.
- The lower the pKa value, the stronger the acid. Since carbonic acid has a lower pKa value than phenol, it is a stronger acid.
Phenol as a Base
- Phenol is not a base but rather an acidic compound.
- It does not have the ability to donate a proton to another molecule, which is a characteristic of bases.
- Ammonia, on the other hand, is a weak base as it can accept a proton to form its conjugate acid.
Phenol's Reaction with Litmus
- Phenol is slightly acidic in nature and can turn blue litmus paper red.
- Litmus paper turns red in acidic solutions and blue in basic solutions.
- Therefore, phenol would be able to change the color of litmus paper, indicating its acidic nature.
In conclusion, the correct statement is that phenol is a weaker acid compared to carbonic acid. It is not a base like ammonia and can exhibit acidic properties by changing the color of litmus paper.
