'''Notes:'''
 
-
* An additional 2-3 mL H<sub>2</sub>O was added to each solution to aid the dissolving of the PVOH
 
-
* Heat was reduced when solutions began to boil too rapidly
 
-
* While transferring solutions to Teflon dishes, loss of sample within the small beakers (sample loss = incomplete sample transfer)
