This question is in reference to my lab: Determination of Acetic Acid (using vinegar as a titration). 5ml of vinegar was used in the titration and 1M NaOH.
I need to know how to calculate the data for my “Vinegar Sample 1” . I have 6 question marks that I am not sure how to calculate. After you show me how to do it, I can calculate my other samples.
Thank you kindly!
CH3CO2H + NaOH → NaCH3CO2 + H2O
