You prepare a buffer solution from 10.0 mL of 0.100 M MOPS (3-morpholinopropane-1-sulfonic acid) and 10.0 mL of 0.084 M NAOH. Next, you add 1.00 mL of 7.87 x 10-4 M lidocaine to this mixture. Denoting lidocaine as L, calculate the fraction of lidocaine МOPS present in the form LH*. K, = 6.3 x 10-8 CH3 NH fraction as LH* = CH3 Lidocaine K = 8.7 x 10-7
