Question

these solutions (2-5) will each be in their own 50 mL volumetric flask.

assigned pH for buffer system: 4.75

acid/base pair to use: acetic acid and sodium acetate

	concentration of acetic acid	amount of acid to add	concentration of sodium acetate	amount of base to add
unit	molarity	g or mL (circle one)	molarity	g or mL (circle one)
solution 2	0.05		0.5
solution 3	0.10		0.5
solution 4	0.50		0.05
solution 5	0.50		0.10

Sample calculation for acid (solution 2-5):

Sample calculation for base (solution 2-5):

You will prepare 4 different 50 mL solutions from the table above. Once you have the calculated amount of acid (g or mL) and base (g or mL) in the correct flask, what should you do to finish preparing each solution? Describe the steps you will take to make this solution.

Finally, transfer each solution to a container for storage.

Answer 1

Serial	Conc. of acetic acid	amount of acid to add	conc. of sodium acetate	amount of acid to add
Unit	Molarity	g or ml (circle one)	Molarity	g or ml (circle one)
Solution 2	0.05		0.5
Solution 3	0.10		0.5
Solution 4	0.50		0.05
Solution 5	0.50		0.10

By using given data and molar concentration , we will find out the amount.
