How would you prepare 1.000 L of a 1.000 mole L?1, pH 7.50 Tris-aka, tris(hydroxymethyl)aminomethane-buffer? You have pure Tris?HCl, {(HOCH2)3NH+,Cl?}, a pH meter, 1.00 M HCl and 1.00 M NaOH, and all of the pure water and glassware you need. Carefully go through all mathematical steps, and then describe in detail how you would make the buffer in the laboratory
