TO FIND ?H FOR A REACTION WHICH IT IS NOT POSSIBLE TO MEASURE THE ENTHALPY CHANGE DIRECTLY
? In this experiment you are going to find ?Hreaction for the decomposition of sodium hydrogen carbonate:
2NaHCO3 (s) --> Na2CO3(s) + CO2(g) +H2O(l) by an indirect method.
You are going to experimentally determine ?Hreaction for the reactions:
Na2CO3(s) + 2HCl(aq)-->2NaCl(aq) + CO2(g) +H2O(l)
and NaHCO3(s)+ 2HCl(aq)--> NaCl(aq) + CO2(g) +H2O(l)
and use your experimental values to find ?Hreaction for the decomposition of sodium hydrogen carbonate.
