1.1. Write a balanced equation for the reaction of acetic acid (as an aqueous solution) with solid sodium bicarbonate, showing all ions present. Make sure you show states. What gas is formed in this reaction? 1.2. How many moles of sodium bicarbonate are present in the 5.00 g? 1.3. How many moles of gas would be produced if this amount of sodium bicarbonate reacted completely with acetic acid, which you added as vinegar?

1- Small bottles (500 water or soft drink bottles).
2- Balloons
3- about 500 mL of vinegar
4- About 50 g of baking soda (baking powder can be used)
5- small spoon
Safety
None of the chemicals used in this experiment are hazardous.
Procedure
1. Use three dry empty water bottles (any size, lager size
0.500 L is better). Add around 100 mL (4 tablespoons).
Make sure you label the bottle.
2. Place one teaspoon (or 5.00 g if you have kitchen scales)
of sodium bicarbonate into first balloon, two teaspoon in
the second and three teaspoon in the third.
3. Carefully attach one balloon to the top of each bottle or
glass without letting any of the sodium bicarbonate tip
out yet.
4. Tip the solid powder into the vinegar, making sure all of
the solid powder is transferred down into the glass.
5. Record your observations in the corresponding sections
in this document based on your experiments, then answer
all questions. You will also need to take some photos and
include them in this document. Please make sure that
your face is visible in all the photo.
6. Save this completed worksheet as a single pdf
document and submit through the moodle before the due
date.
7. Please show all working and correct units in your
calculations – simply providing a numerical answer will
not receive all marks even if this is correct. Make sure
that you correctly show subscripts and superscripts as
required in any chemical symbols.
