Calculate the pH of a 1.41×10-2 M solution of the decongestant ephedrine hydrochloride if the pKb of ephedrine (its conjugate base) is 3.86.
ephedrine hydrochloride is salt of weak base and strong base
for such salts
pOH = 1/2 [pKw + pKb + log C]
pKb = 3.86
C = 0.0141 M
pOH = 1/2 [14 + 3.86 + log 0.0141]
pOH = 8.00
pH = 14 - 8.0
pH = 6.0
