Data Tables:

Table $1-$ Part A Initial concentrations of $F{e}^{3+}$ and $SC{N}^{-}$in Unknown Mixtures

Table $2-$ Part D Spectroscopic Method $($Using the Calibration Curve$)$

Plot a graph of Abs vs $FeSC{N}^{2+}$ and use this graph to calculate $FeSC{N}^{2+}$ eq for part A $($Table $1).$

Calculate Keq values for the solutions in Table $1,$ by preparing an I.C$.$E$.$ table using $F{e}^{3+}$ initial,

$[SC{N}^{-}{]}_{\text{i}\text{n}\text{i}\text{t}\text{i}\text{a}\text{l}\text{,}}$ and $[FeSC{N}^{2+}{]}_{eq}$ values.
