1)Methadone, C21H27ON, is a drug used to treat individuals suffering from opioid addiction. Methadone is a weak base with pKb=5.60. Methadone is frequently administered in the form of its hydrochloride salt, methadone hydrochloride (C21H27ONHCl). Calculate the pH of a 0.400M solution of methadone hydrochloride.
[Refer to page 204 in the lecture note manual for a similar problem or watch the Tutorial Video on Moodle for the calculation of the pH of a solution of a drug salt]
Report your answer to two decimal places
2)Calculate the molar solubility of manganese hydroxide in a solution buffered at pH = 10.25.
Mn(OH)2 (Ksp = 1.9Ã10â13)
