LAB D Flashcards
1
Q
Go over any calculations from Lab D in Workbook
A
2
Q
why is a rough titration needed when titrating unknown acid?
A
to get an idea of the volume needed before doing accurate titrations
3
Q
why isnt a rough titration needed when standardizing NaOH?
A
we can estimate the volume needed from the concentration of sulfamic acid and NaOH solutions
4
Q
why do use the sample with the smallest mass for a rough titration
A
-so we know it will be at least that number
5
Q
what is learning objective of Lab D
A
-titration experience
6
Q
what is the scientific purpose of Lab D
A
-determine molar mass of an acid by volumetric analysis
