Please use correct units and show sig digs.
Practice: You need to prepare 3.00 L of a 0.500 M buffer of pH 5.80. The reagents available to you are listed in Table 1. Table 2 shows the pK s for the acids in Table 1 Table 1: Potassium dihydrogencitrate Malonic acid Sodium hydrogen succinate Disodium maleate HCL NaQH (230.2 g/mol) (104.1 g/mol) (140.1 g/mol) (160.0 g/mol) (12.0 M) (10.0 M) Table 2: Acid citric malonic ucciniC maleic pKa 3.14 2.83 4.21 1.83 pKaz 4.77 5.69 5.63 6.07 pKa, 6.39 a. Which of the reagents from Table 1 would you use for making the buffer? b. Calculate how much of each reagent (and water) you would use to make this buffer. From Table 1, select a second set of reagents that you could use to make a buffer of the same pH and concentration c. d. How much of each reagent and water would you use to make this buffer?Explanation / Answer
