In my AP Chem class, I have to design a lab, which results in finding the rate of a reaction. For example, a lab we did in class was reacting Magnesium metal with HCl, forming Hydrogen gas. We collected this gas in a eudiometer and kept a record of the gas volume as the reaction went on. From this, you could make a graph and find a general rate of reaction.
I can't use this example for my own lab, but I a having a hard time coming up with ideas with how to make this lab successful. We can use temperature, volume, mass, concentration, etc in this lab.
If anyone has any good ideas, please let me know!!!

IDEA FOR CONCENTRATION:
Attain 3 different concentrations of acid and measure 30cm cubed of each.
add marble chips to each solution (8g advised)
This should be done in a conical flask that should be placed on a balance.
Note the initial Mass and start the stopwatch.
note the mass every 30 seconds for 10-15 minutes
repeat the procedure with the other two concentrations of acid.
Plot the results for all three experiments on 1 graph
explain the shape of the curves and the effect concentration has on the reaction.
