**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.

### 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:
  - \(0\)
  - \(6.3 \times 10^{-31}\)
  - \(4.6 \times 10^{-16}\)
  - \(2.1 \times 10^{8}\)
  - \(5.3 \times 10^{6}\)
  - \(8.6 \times 10^{-11}\)
  - \(2.8 \times 10^{-8}\)
  - \(1.2 \times 10^{-8}\)
  - \(4.1 \times 10^{-11}\)

- Use the "RESET" button to clear your input if needed.
