### Dissociation Equilibrium of Ionic Compounds

**Problem 2:**

The solubility of an ionic compound M₂X₅ is 4.7 x 10⁻⁸ g/L and its molar mass is 356.2 g/mol.

#### Steps to Solve:

a. **Write out the dissociation equilibrium for this ionic compound. (States of matter must be included.)**

b. **Complete the ICE box for the equilibrium.**

c. **Determine the equilibrium concentrations for both ions.**

d. **Write the \( K_{sp} \) expression and solve for the value.**

### Explanation:

1. **Dissociation Equilibrium:**
   The dissociation equation for the compound should specify the states of matter. 

2. **ICE Box for Equilibrium:**
   The ICE box (Initial, Change, Equilibrium) helps to track the concentrations of reactants and products through the reaction.

3. **Equilibrium Concentrations:**
   Calculate the concentrations of the ions at equilibrium using the solubility and the dissociation equation.

4. **\( K_{sp} \) Expression:**
   Write and solve the solubility product constant expression for the ionic compound.
