hello everyone i hope you can help me out....
Today my chemistry teacher gave us this experiment:
to find out why the percent yield of the production of CO2, that you get from the reaction when a alka-selzer is put into water, is only 1-6%
the chemical reaction is as follows
NaHCO3 + H20 ---> CO2 + H2O + NaOH
I used 1.78 grams of Alka-selzer (NaHCO3) or 0.02119 moles
After doign the math on paper i should be getting 0.02119 moles of CO2, but in reality i can only collect .000447 moles.
Could anyone explain as to why it is such a lower percent yield?
My teacher also said that the secret lies within the indegeridents, (which are asprin, and citric Acid)
(please forgive my spelling i was in a rush to get to work)
Thanks in advance,
Greg
