Given 0.5 M solution of acetic acid (pKa = 4.76) and solid sodium acetate (Mr = 82 g/mol), describe how you would go about preparing 500 mL of 0.2M acetate buffer pH 4.0.
Prepare 100mL of a 0.2M acetate buffer solution of pH =4.76 (using 17.6N acetic acid and sodium acetate). a. Calculate the volume of acetic acid and weight of sodium acetate necessary to prepare the buffer solution. pKa of acetic acid is 4.76
4. How much of (in mL) 0.15 M acetic acid (pKa 4.76) is needed to mix with 40 mL of 0.15 M sodium acetate to make a buffer of pH = 4.50 of 250 mL? (molar mass of acetic acid and sodium acetate are 60.0 g/mol and 82.0 g/ml, pKa of acetic acid is 4.76) (extra 10 pt)
calculate the pH for a buffer solution made from a 3:1 ratio of 0.1 M acetic acid and 0.1 M sodium acetate. (pKa of acetic acid is 4.76)
You need to prepare an acetate buffer of pH 6.29 from a 0.704 M acetic acid solution and a 2.48 M KOH solution. If you have 575 mL of the acetic acid solution, how many milliliters of the KOH solution do you need to add to make a buffer of pH 6.29? The pKa of acetic acid is 4.76. You need to prepare an acetate buffer of pH 6.29 from a 0.704 M acetic acid solution and a 2.48 M...
6. How many mL of 0.2 M sodium acetate should be added to 200 mL of 0.2 M acetic acid to make a buffer of pH 5.5? (refer to Table 2-2 on page 60 for pKa values). What is the molarity of the resulting buffer with respect to acetate (acetate + acetic acid)? 7. How many mL of 0.2 M HCl should be added to 50 mL of 0.2 M Tris base (Trishydroxymethyl aminomethane) to make a buffer of pH...
