For this assignment, you will be designing a lab to investigate factors that affect the rate of a reaction. You are not required to conduct the experiment, but it may be beneficial to do so if you can acquire the materials needed for your design.

The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is ingested. Each tablet contains aspirin (acetylsalicylic acid), citric acid, and sodium bicarbonate. As the tablet dissolves in water, the bicarbonate ions in the tablet react with the hydrogen ions from the acids that are also contained in the tablet. The carbon dioxide gas that is produced by the reaction is what causes the bubbling that can be observed.

HCO3- (aq) + H+ (aq) → H2O (l) + CO2 (g)

In this investigation, you will design an experiment to determine what two factors will increase the rate of the reaction above, and then compare the effectiveness of each factor. It is important that in each investigation you control all other variables that could affect the rate of the reaction.

The document that you submit to your instructor should include the following sections: materials, procedure, and conclusion. Instructions and suggestions are provided below to help you make sure that each section of your document is complete.

I really have no idea what I'm doing and I'm just writing a bunch of stuff so I can look at another paper to copy because I hate chemistry and have no idea how to do this. I need serious help with this, I hate it so much and want to get it over with. What the heck do I do with this, what do I do man, what do I do. I need help with this stuff, please, if you'd be so kind as to allow this to pass through so I can get to the paper, you stupid website. I hate chemistry so much and I wish it a horrible painful death, okay there. I said it,...
