There are several different methods used to make sodium hydroxide. In order to use a standardized solution, the solution must be prepared. The labels have fallen off of three bottles thought to contain hydrochloric acid, or sodium chloride solution, or sodium hydroxide solution.
Next time to improve the data and the results of this experiment, student should carefully weigh the Potassium acid phthalate to the accurate measurement and patiently titrate the solution not to overdose.
Sodium hydroxide a base is typically used as a standard to determine the concentration of acids. The end point of the titration is the first permanent color change. The rest of the experiment for section 2 is similar to section 1.
A diluted standardization NaOH were prepared in a mL volumetric flask.
