How to do this remote lab
On the pages that follow, read the captions, check out the photos, and watch videos
No sound on videos, aside from background music, for accessibility reasons
Record observations and data
TAs provide starting volume (0.80 - 1.20 mL)
Recalculate theoretical yield from starting volume.
Keep track of product loss to calculate your 'actual yield' by subtracting from theoretical
Every student will turn in data & observations along with the Partner Agreement
