Question

Based on the data from table 4.1 

Table 4.1: Part A –Acetate Buffers

	0.5 M sodium acetate (mL)	0.5 M acetic acid (mL)	sodium acetate (mol)	acetic acid (mol)	Ratio [sodium acetate] [acetic acid]
1	1.0	9.0	0.0005	0.0045	0.1111
2	3.0	7.0	0.0015	0.0035	0.4286
3	5.0	5.0	0.0025	0.0025	1.0000
4	7.0	3.0	0.0035	0.0015	2.3333
5	9.0	1.0	0.0045	0.0005	9.0000

calculate the new mole ratio of sodium acetate to acetic acid after the addition of 1.0 mL of 1.0 M NaOH. Show one complete sample calculation only.
