Question: Fe(III) precipitates from acidic solution by addition of OH - to form Fe(OH) 3 (s). At what concentration of OH - will [Fe(III)] be reduced

Fe(III) precipitates from acidic solution by addition of OH^- to form Fe(OH)₃(s). At what concentration of OH^- will [Fe(III)] be reduced to 1.0 × 10^-10 M? If Fe(II) is used instead, what concentration of OH^- will reduce [Fe(II)] to 1.0 × 10_-10 M?
