STOICHIOMETRY LAB REPORT
· Show the balanced equation of the reaction that you had occur in this lab
· Record the data in a table of vinegar, and baking soda used; what you observed while the reaction took place for each time you did the experiment; record the circumference of your balloon; write down any factors that were successful or a failure
· Do any of the balloons inflate? How much?
· Is there a relationship between the volume of vinegar used and the volume of the balloon? Is there a point at which more vinegar does not increase the size of the balloon?
· Is there a limit to the quantity of gas that can be produced from one teaspoon of baking soda?
· Using what you know about chemical reactions, can you explain why adding more of one reactant would not increase the quantity of product produced?
· Which of the two reactants is left in each of the four bottles after the reaction stops? (Hint: if you are not sure, open the container. Add a drop of vinegar. Does a reaction occur? If not, add a pinch of baking soda. Now what happens?)
· Which reactant in each bottle limited the volume of gas formed, i.e., which is the limiting reactant?
