You need 500.0 mL of a buffer at pH 10.00 based on phenol (Ka =1.6x10^-10 ; 91.113 g/mol). You begin by dissolving 7.107 g ofsolid phenol in 200 mL of water. You have available solutions ofboth 0.250 M HCl, and 0.320 M NaOH. You will complete the processby adding deionized water until reaching the line on the volumetricflask. What volume (in mL) of which reagent (HCl of NaOH)should you add to end up with the desired buffer?
