From the following list, choose 2 reagents and calculate the quantities that are required to make 250 mL of a 0.200 M buffer with a pH of 3.50. If the reagent is a solid, calculate mass; if the reagent is aqueous, calculate volume. Water is also available. List of reagents: 1.00 M HX (pKa = 5.15) Solid HY (pKa = 3.25, molar mass = 100.0 g/mol) Solid NaX (molar mass = 82.55 g/mol) 1.00 M HCl 1.00 M NaOH
