October 22: Aspirin Titration Experiment

Description:

A titration is used to find the amount of a substance through causing a reaction that changes the pH. An indicator is used to show when the reaction is complete.

In this experiment, the aspirin(acertylsalic acid) reacted with  sodium hydroxide. Neutralization produces water and a salt, therefore:

           Equation- C₉H₈O₄(aq) + NaOH(aq) -> C₉H₇O₄Na(s) + H₂O

Data Processing:

We can use this equation to find out the number of moles of the aspirin in the titration through finding the number of moles of NaOH needed to react with the aspirin and how many moles there are present. The second part of the data processing is to find how much aspirin you get from each tablet, spending the same amount of money. First, you have to find the price of one tablet. Once you do that, you have to scale your values to the same price. Then you can compare the two amounts of aspirin to see which one contains more.
