Tris is an abbreviation for tris (hydroxymethyl) aminomethane, which is a weak base. Calculate how many grams of tris (mw=121.14g/mol) are needed to make 25mL of 0.10M tris solution. Calculate how many mL of 0.25M HCl are needed to convert half of the moles of tris present in 25mL of 0.10 M tris solution to protonate tris (trisH^+). The relevant hydrolysis equilibrium is tris+ H^+ -> Htris^+
