Vedclass · Answer

(C) The reaction of a compound with $NaHCO_3$ depends on its acidity. Compounds that are more acidic than carbonic acid ($H_2CO_3$,$pK_a \approx 6.35$) will react with $NaHCO_3$ to evolve $CO_2$ gas.$1$. Squaric acid $(pK_a \approx 1.5)$ is a strong acid and reacts with $NaHCO_3$.$2$. Salicylic acid $(pK_a \approx 2.97)$ is more acidic than carbonic acid and reacts with $NaHCO_3$.$3$. Acetic acid $(pK_a \approx 4.76)$ is more acidic than carbonic acid and reacts with $NaHCO_3$.$4$. Carbolic acid (phenol) $(pK_a \approx 10)$ is a very weak acid,significantly less acidic than carbonic acid. Therefore,it does not react with $NaHCO_3$ to evolve $CO_2$ gas.
