You are in charge of making a Tris buffer at pH 7.5. You could start with solid Tris base as you did in lab, but you found stock solutions of 1.0M Tris base and 1.0M Tris Hydrochloride (the conjugate acid form) in the lab and decided to make the buffer with those. How much of each of the stock solutions would you mix together to make 200.0 mL of 1.0M Tris buffer at pH 7.5?
