You can also use an erlenmeyer : if you are using the science journal app to record your titration curve, an erlenmeyer flask will not work.
Titration curve allows you to determine the amount of acid in a sample, even if you did not perform the titration experiment yourself (and therefore could not write down the amount of titrating solution used). Besides some fluctuations from stirring the solution, the light intensity values should have stayed relatively constant until the titration endpoint was reached.
For your calculations you need to know how much time into the titration the equivalence point occurred. In an original titration curve, this endpoint is characterized by a sharp increase of ph in your sample solution.
