3. TRIS, N-tri[hydroxymethyl]aminomethane, is one of Good's buffers. In its unprotonated form, it is called TRIS base (A). Its protonated form is called TRIS acid or TRIS-HCI (HA). The pKa for TRIS buffer is 8.30 at 20°C. If you mix 20 mL of 0.2 M TRIS (base form) and 20 mL of 0.1M HCl, what is the pH of the resulting solution? a. 7.00 b. 8.30 c. 7.45 d. 8.00 e. 7.35
