Explanation:

There are three possible steps for calculating the #"pH"# of a basic solution.

#1)# Calculate #["OH"^-]#. For a strong base, this will be the concentration of the base. For a weak base, use #["OH"^-] = sqrt ("K"_"b" xx ["BOH"])#.

#2)# Calculate #"pOH"# or #["H"^+]#. Either use #"pOH" = -log["OH"^-]# or #["H"^+] = ("K"_"w")/(["OH"^-])#

#3)# Calculate #"pH"#. Either use #"pH" = 14-"pOH"# or #"pH" = -log["H"^+]#
