Question

Using the table provided what would be the Equilibrium [FeNCS2+],M of each?

**Table 22.1: Standard Solutions for FeNCS²⁺ Ion Beer-Lambert Plot** This table outlines the preparation of standard solutions for constructing a Beer-Lambert plot specific to the FeNCS²⁺ ion. Each solution contains varying amounts of sodium thiocyanate (NaSCN) while maintaining a constant concentration of iron(III) nitrate [Fe(NO₃)₃]. **Solution Composition:** - **mL of 2.00 × 10⁻¹ M Fe(NO₃)₃ in 0.10 M HNO₃:** This column specifies that each solution contains 10.00 mL of this iron nitrate solution. - **mL of 2.00 × 10⁻³ M NaSCN in 0.10 M HNO₃:** This column details the volume of sodium thiocyanate solution added, ranging from 0.00 mL to 5.00 mL across the six solutions. - **Total Volume (mL):** Each solution has a final volume of 50.00 mL. **Solutions:** 1. 0.00 mL NaSCN 2. 1.00 mL NaSCN 3. 2.00 mL NaSCN 4. 3.00 mL NaSCN 5. 4.00 mL NaSCN 6. 5.00 mL NaSCN This systematic variation in NaSCN volume while maintaining a constant Fe(NO₃)₃ concentration allows for the Beer-Lambert law application, aiding in the determination of the FeNCS²⁺ ion's absorbance characteristics.
