In this experiment, acetylsalicylic acid is the only species that will hydrolyze and consume some of the added base solution. The purpose of the back titration is to determine how much acetylsalicylic acid is present in the sample. If the back titration showed that none of the added base is consumed in the reaction, what does that indicate about the acetylsalicyclic acid?

Answer #1

Acetylsalicylic acid reacts with base and hydr

If the titration flask contains acetylsalicylic acid in it, then it will react with sodium hydroxide. If there is no acetyl salicylic acid in the titration flask at all, then the added base will not be consumed in the reaction.

Thus, it can be concluded that there is no acetyl salicylic acid present in the titration flask.

    In this experiment an EDTA titration was performed. Another common type of titration is an acid-base titration. Specifically, a neutralization titration can be used to determine the concentration of a strong acid if it is titrated with a strong base whose concentration is known. This method uses stoichiometry to determine the unknown acid's concentration. Let's say a student had 1.0 M sodium hydroxide ( a? ) and found a solution of sulfuric acid 2 04) whose label had faded.
