Answered by shubhamoybiswas05

CH3COOH (acetic acid) has a carboxylic acid group and is an organic acid, so it will react with sodium bicarbonate (NaHCO3) to produce brisk effervescence of carbon dioxide gas. Only stronger acids like CH3COOH give brisk effervescence on reacting with NaHCO3.

HOPE IT HELPS THANK YOU

sarbani30: i don't think that is the correct answer

sarbani30: because its not in the options..

shubhamoybiswas05: Sorry my answer is wrong it will be HCl , because HCl is an acid and it reacts with the metal carbonate Na2CO3 to give CO2 (carbon dioxide) , H2O and NaCl ( sodium chloride). As, it involves the release of carbon dioxide a brisk effervescence is seen.

sarbani30: ok no problem.. Thank you for the answer :)
