Thank you! I currently do not have access to my lab right now due to the coronavirus, but definitely can when I am able to return to campus. Do you have any material in particular that you are interested in seeing?

Here is a link to another video I have already made on standardization of NaOH: kzread.info/dash/bejne/l4Rkt9mJqMLckrA.html

The equilibrium is shifted to the far right as pKa of CH3COOH

Is this how you extract acetic acid out of vinegar ?

No way your numbers will be accurate. The NaOH should be freshly prepared and standardized. Water for NaOH should be boiled to remove dissolve CO2. NaOH titrant should be stored with a CO2 absorber to remove CO2 from air. The endpoint was overshot. It should not stay pink. It should fade to clear after 15-30 sec due to CO2 from air.
