Carboxylic Acids, Esters and Amines
« on: January 21, 2011, 04:52:29 AM »
Can anyone please tell me what reaction occurs between:
a. glacial acetic acid + sodium bicarbonate
b. triethylamine + sodium bicarbonate
c. benzoic acid + sodium bicarbonate

a. glacial acetic acid + hydrochloric acid
b. triethylamine + hydrochloric acid
c. benzoic acid + hydrochloric acid

Please give the balanced chemical equation and the reasons why. Thank you so much!

Oh, I'm sorry. It's just that I'm not really good in Chemistry, nor do I fully understand it so I'm kind of afraid of the humiliation that I might get from posting my answers here.

Well, I've tried to search for the answers and here are the results I've obtained.
By the way, here's the sequence of our experiment: sample + H20, then we added NaHCO3 into the solution (sample + H20), and lastly, we added HCl to the solution (sample + H2O + NaHCO3).
a. CH3COOH + H2O + NaHCO3 --> CH3COONa + H2O + H2CO3
    since the H2CO3 is unstable, it further decomposed into water & carbon dioxide:
    CH3COOH + H2O + H2CO3 --> CH3COONa + 2H2O + CO2
b. C6H15N + H20 + NaHCO3
    i have no idea about this one..
c. C6H5COOH + H2O + NaHCO3 --> C6H5COONa + 2H2O + CO2

Is it correct? Please, I really need help.

For rxn of sodium bicarbonate: it release CO2 in presence of strong acid
For rxn of HCl: use common ion effect

Chemistry is a subject in which even the Professor can get confused at any time.
