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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd86e2176-2b92-4a94-a128-f6a0aba0ae4d%2Ff09e1cb3-92f3-42a3-90d8-fcff5263a96f%2Fvsd8so_processed.jpeg&w=3840&q=75)
