Answer:

#color(blue)[["OH"^-]]=color(blue)[1xx10^-11" M"#

Explanation:

At #"25"^@"C"#,

#color(white)(----)color(magenta)[["OH"^-]["H"_3stackrel"+""O"]]=color(magenta)[1xx10^-14" M"^2]#

If #["H"_3stackrel"+""O"] = 1xx10^-3" M"# then...

  • #color(magenta)(["OH"^-]["H"_3stackrel"+""O"])=color(magenta)[1xx10^-14" M"^2]#
  • #["OH"^-][ 1xx10^-3" M"]=1xx10^-14" M"^2#
  • #["OH"^-]=(1xx10^-14" M"^cancel2)/[ 1xx10^-3cancel" M"]#
  • #color(blue)[["OH"^-]]=color(blue)[1xx10^-11" M"#
