Titration Calculations and Questions
Calculations Made After the Titration Process
considering that the purpose of the experiment is to find the molar mass of the NaOH (base) in order to do this, we use the formula: Molarity (of the acid) * Volume (of the acid) = Molarity (of the base) * Volume (of the base) and then you solve for the Molarity of the acid using algebra |
if you are still confused about the calculations, fast forward to 6:10 in the video above and watch until the end

Questions About the Titration Process
Why don’t you have to dry the conical flask if that’s where the titration occurs?
when you add water to the flask, the concentration of the base will change, but the number of moles will not be affected at all (the moles are what really matters) because you’re are not changing the number of grams or the molar mass of the base (NaOH in this case) and since the reaction occurs in the flask, both the acid and the base will be equally exposed to the water
Why don’t you want to get chemicals on the sides of the flask?
not all of the chemicals will be part of the reaction because they will be stuck on the sides of the flask, thus not all of the parts of the acid or base (depends on which one gets stuck on the sides of the flask) will be part of the titration
