LAB 1: ALKA SELTZER REACTION
Introduction:



Alka-Seltzer is an effervescent (bubbling) antacid and pain reliever for the relief of heartburn and indigestion. Alka-Seltzer relieves indigestion by neutralizing excess hydrochloric acid (HCl) in our stomach. One of the active ingredients in Alka-Seltzer is sodium hydrogen carbonate (NaHCO3), which reacts with HCl and changes it into carbon dioxide gas (CO2) and water (H2O). The fizzing that is seen when an Alka-Seltzer tablet is dropped in acid is the same sort of fizzing reaction that can be seen when baking soda is mixed with vinegar. The chemical equation is shown below.



True or False: Sodium chloride, carbon dioxide, and water are all reactants.



True
False

PROCEDURE:
1. Watch this video.

2. Write down your observations in a chart like the one below to answer the following 4 questions correctly.

Data Table:

Flasks Observations
NaHCO3 before reaction
HCl before reaction
HCl Flask DURING reaction
HCl Flask AFTER reaction


Question: How did you observe NaCl being formed as a product/after the reaction?

a
It formed into solid salt structures.
b
There was foaming as NaCl dissolved.
c
There were bubbles of gas in the reaction.
d
All of the above were signs of NaCl being formed.
Question 5 (1 point)
From the same video as question #2, how did you observe carbon dioxide being formed as a product?



a
A solid precipitate was formed.
b
Gas bubbles formed and bubbled through the flask.
c
A color change occurred.
d
All of the above are signs that carbon dioxide formed.
Question 6 (1 point)
What would happen with the lab IF rather than powder NaHCO3 we used a whole alka seltzer tablet? Remember it would have the same chemical make up, but have a smaller surface area.



a
The rate of the reaction would speed up.
b
The rate of the reaction would slow down.
Question 7 (1 point)
the surface area, increases the reaction rate.
