![**Determining Molar Solubility for Cr(OH)₃ Using an ICE Table**
**Objective**: Determine the molar solubility for Cr(OH)₃ by constructing an ICE table, writing the solubility constant expression, and solving for molar solubility. The solubility product constant (\(K_{sp}\)) for Cr(OH)₃ is \(6.3 \times 10^{-31}\). Complete Parts 1-3 before submitting your answer.
---
**Instructions**:
Fill in the ICE (Initial, Change, Equilibrium) table with the appropriate values for each involved species to determine the concentrations of all reactants and products.
**Equation**:
\[ \text{Cr(OH)}_3(s) \rightleftharpoons \text{Cr}^{3+} (aq) + 3 \text{OH}^{-} (aq) \]
---
**ICE Table**:
| | Cr(OH)₃(s) | ⇌ | Cr³⁺(aq) | + | 3 OH⁻(aq) |
|--------|------------|---|----------|---|----------|
| **Initial (M)** | — | | | | |
| **Change (M)** | | | | | |
| **Equilibrium (M)** | | | | | |
*NOTE: The solid chromium hydroxide, Cr(OH)₃, does not have a concentration change reflected in the ICE table as it is a pure solid.*
---
**Selectable Options**:
Below are possible values and expressions used to fill the ICE table:
* Numeric values (e.g., \(0\), \(6.3 \times 10^{-31}\))
* Algebraic expressions (e.g., \(-x\), \(+3x\), \(6.3 \times 10^{-31} + x\))
* Reset button to clear choices
**Calculate**:
1. Assign initial concentrations for aqueous species.
2. Apply changes in concentrations using variable \(x\) to denote solubility adjustments.
3. Solve for equilibrium concentrations using the \(K_{sp}\) expression.
Use these tools to solve for the molar solubility of Cr(OH)₃ accurately.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa91f799b-1b33-41a5-8f4e-af83231854b4%2F30835486-85ad-41d3-9887-c7b181bcdf78%2Fqfxgybc_processed.png&w=3840&q=75)

![### Determining Molar Solubility for Cr(OH)₃
To determine the molar solubility of Chromium(III) Hydroxide (Cr(OH)₃), follow these steps:
1. **Construct an ICE Table:**
- An ICE (Initial, Change, Equilibrium) table will help visualize the dissociation of Cr(OH)₃ in water and track the concentration changes.
2. **Solubility Constant Expression:**
- Use the Ksp (Solubility Product Constant) to write the equilibrium expression for Cr(OH)₃.
- Given: Ksp = 6.3 × 10⁻³¹.
3. **Calculate Molar Solubility:**
- Solve the Ksp expression to find the solubility (S) of Cr(OH)₃ in moles per liter (M).
#### Input Section:
- An interactive input allows you to enter the calculated molar solubility value as \( S_{\text{Cr(OH)}_3} = \) [Input Box] M.
#### Options:
- Several possible values for molar solubility are presented as choices:
- \(0\)
- \(6.3 \times 10^{-31}\)
- \(4.6 \times 10^{-16}\)
- \(2.1 \times 10^{8}\)
- \(5.3 \times 10^{6}\)
- \(8.6 \times 10^{-11}\)
- \(2.8 \times 10^{-8}\)
- \(1.2 \times 10^{-8}\)
- \(4.1 \times 10^{-11}\)
