Please find the pH calculation.
Kb=1.5•10-12
use ICE table if needed. Result should come out to be about 1.66
![**System #12: 0.10 M Iron (III) Chloride (source of Fe(H₂O)₆³⁺ complex)**
**Reaction with water:**
\[ \text{[Fe(H₂O)₆]³⁺} + \text{H₂O(l)} \rightleftharpoons \text{[Fe(H₂O)₅(OH)]²⁺} + \text{H₃O}⁺ \]
**K\(_b\) of \([Fe(H₂O)₅(OH)]²⁺\) = 1.5 × 10⁻¹²**
**pH Calculation:**
- **Predicted pH:** 1.66
- **pH Paper:** 2
- **pH Meter:** 1.54
Note: The reaction describes the interaction of the iron (III) chloride complex with water, indicating the formation of hydrolyzed species and hydronium ions, affecting the pH of the solution. The K\(_b\) value represents the base dissociation constant for the hydrolyzed complex. The different pH values show predicted and measured acidity levels.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F290e4581-ac4b-484d-9123-17cd55051d66%2F548dd4c5-4300-414a-8b25-5a526dba9ef7%2F9qct0e_processed.jpeg&w=3840&q=75)
