Question

(In Acid-Base Titrations and Standardization Experiment ) Why should you not store NaOH in a glass container? Why you should rinse out any glass container that has come in contact with NaOH each day after use?

Answer 1

Since glass will react with strong bases, NaOH solutions stored for any extended period of time should be kept in plastic bottles. sometimes NaOH solution can cause glass stoppers to become stuck.

At the end of the day if the glass container that has come in contact with NaOH should be throughly rinsed with water, because NaOH can change the surface of glass and make it basic. This will give wrong results when the experiments are carried out in the next day.
