Heated too long

 I got distracted with the CO2 aspect of the experiment and left the solution on the heat to long. The water started to boil, which resulted in the precipitation of salts out of the solution. Because of this, my results from experiment 4 are very imprecise.

I discovered that 10mL of Acetic acid and 3g of Sodium Hydrogen Carbonate can produce between 100 and 200mL of CO2.  As a result, I have more CO2  than I need for each test. Hopefully I can save the excess for another experiment.
