My goal is prepare a 100.00 mL of a buffer with a pH = 3.500 and a total common ion concentration of 0.100 M. I have available to me, bottle of 1.00 M of acetic acid, formic acid, ammonia, hydrochloric acid, sodium hydroxide, sodium formate, sodium acetate, and ammonium chloride. What do you suggest I do in order to obtain the correct pH and total common ion concentrations that I listed above? I need to use glassware that is correct to three decimal places
