Titration Lab Abstract.
The molarity of HCl was determined by titrating the acid, HCl, with a standard base solution, NaOH. It was determined that there was a 1.356 M concentration of HCl, with a very minimal percentage of error of 3.14%.
In order to determine the concentration of an acid in a solution, a neutralization reaction will need to be preformed. In this case the concentration of HCl needs to be determined. This is done by completing a titration of HCl with a
The solution of known concentration is called the standard solution, it this case,
This titration will continue until the solution has reached its end point, where the phenolphthalein indicator causes the solution to change from a clear solution to a shade of red, indicating the end point.
The procedure used in this experiment is located on the Â¡Â¥Titration LabÂ¡Â¦ handout. There were no variations to this procedure.
