Title : Determination of Ksp of Fe(OH)3

Determine the solubility constant of iron (III) hydroxide through spectrophometric analysis of soluble Fe3+ plus pH measurements .Two diluted concentrations of FeCl3 analytes ( o.01 M and 0.05M ) were used to form Fe(OH)3 precipitate. The solubility constants were determined to be …………. And ……….. for both FeCl3 (0.01 M and 0.05M) samples ; both of solubility constants were compared against the activity coefficient values of the same compound and it was calculated as …….. and ……. For samples 1 and 2 respectively .
