Problem: Codeine (C18H21NO3) is a derivative of morphine that is used as an analgesic, narcotic, or antitussive. It was once commonly used in cough syrups but is now available only by prescription because of its addictive properties. If the pH of a 1.7 X 10-3-M solution of codeine is 9.59, calculate Kb.

🤓 Based on our data, we think this question is relevant for Professor Bindell's class at UCF.

Step 1

pOH = 14 - 9.59 = 4.41


[OH-] = 10-pOH[OH-] =10-4.41

[OH-] = 3.89x10-5 M


Step 2


Step 3

[B] = 1.7x10-3 - 3.89x10-5 = 1.661x10-3 M

[HB] = 3.89x10-5 M
