		+	* Soak films in CuSO<sub>4</sub> and NaSO<sub>4</sub> solutions for ISE.

		+	==Acetylation of PVOH to Make PVAc==
		+	* Three solutions of PVOH and acetic acid (HAc) were prepared at the following mole percentages of HAc to PVOH: 20%, 40%, 60%, and 100%.
		+	* 5-DTAF was added to each solution such that the dye would react with 0.01% of the hydroxide groups of PVOH.
		+	'''MW repeating unit of PVOH, [C<sub>2</sub>H<sub>3</sub>OH]<sub>n</sub>: 44.06 g/mol'''
		+	'''1 g PVOH × (1 mol [C<sub>2</sub>H<sub>3</sub>OH]<sub>n</sub>/44.06 g) × (1 mol OH/1 mol [C<sub>2</sub>H<sub>3</sub>OH]<sub>n</sub>) = 0.022696 mol OH/g PVOH'''
		+
		+	'''MW 5-DTAF: 495. 28 g/mol'''
		+	'''0.022696 mol OH × 0.0001 = 2.2696 × 10<sup>-6</sup> mol 5-DTAF'''
		+	'''2.2696 × 10<sup>-6</sup> mol 5-DTAF × (495.28 g/1 mol 5-DTAF = 0.001124 g 5-DTAF'''
		+
		+	* Please refer to [[User:Moira_M._Esson/Notebook/CHEM-581/2012/11/14\|Moira Esson's entry]] for notes and observations about the reaction.
