Oxycodone (C18H21NO4), a narcotic analgesic, is a weak base with pKb=5.47.

a.Calculate the pH in a 0.00230M oxycodone solution.

b.Calculate the concentrations of C18H21NO4 in a 0.00230M oxycodone solution.

c.Calculate the concentrations of 4HC18H21NO4+ in a 0.00230M oxycodone solution

d.Calculate the concentrations of H3O+ in a 0.00230M oxycodone solution.

e.Calculate the concentrations of OH− in a 0.0023 M oxycodone solution.

I'm messing up a calculation somewhere so now all of them are wrong. please show work so i can learn how to do this

± Determining the pH of a Weak Base and the Percent Ionization of a Weak Acid Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency of a weak acid or base to ionize can be quantified in several ways including Ka or Kb, pKa or pKb, and percent ionization*. *This assumes that species of equal concentrations are being compared as percent ionization is affected by concentration. Part A Pyridine is a...
