Hi all, I hope you guys can help me out here.
My question relates to the reaction of sodium carbonate with hydrochloric acid.
I know that Na2CO3(s) + 2HCl(aq) --> 2NaCl(aq) + H2O(l) + CO2(g)
But what about Na2CO3(aq) + 2HCl(aq)
ie. when the sodium carbonate is first dissolved in solution before adding the acid?
I have searched multiple resources but can find no conclusive answer as generally the states are not given.
Would the correct equation be: Na2CO3(aq) + 2HCl(aq) --> 2NaCl(aq) + H2O(l) + CO2(aq)
or: Na2CO3(aq) + 2HCl(aq) --> 2NaCl(aq) + H2CO3(aq)
or possibly neither of these?
I realise that the actual reaction is much more complicated than either of these equations would indicate due to the equilibriums involved with CO2(aq) and H2CO3(aq) in the above equations, but I would very much like to know the correct way to give the simple equation.
I don't mean to sound harsh but please only provide an answer if you are absolutely certain that it is correct, speculation is welcome but please ensure it is stated as such.
Any help would be very much appreciated
