You prepare a solution from 10.0 mL of 0.100 M MOPS buffer (3-morpholinopropane-1-sulfonic acid) and 10.0 mL of 0.082 M NaOH. Next, you add 1.00 mL of 1.35 × 10-6 M lidocaine to this mixture Denoting lidocaine as L, calculate the fraction of lidocaine present in the form LH .MOPS Buffer Ka = 6.3 × 10-8. Lidocaine Kb = 8.7 × 10-7, calculate the fraction of lidocaine present in the form LH
