![**Question 2**
Calculate the hydroxide ion concentration for a solution with \((\text{H}_3\text{O}^+)_{eq} = 0.00004 \, \text{M}\).
*Hint: \(K_w = K_a \times K_b\)*
---
**Note:**
- The prompt indicates a need to calculate the hydroxide ion concentration using the relationship between the ion product of water (\(K_w\)) and the equilibrium concentrations of hydronium (\(\text{H}_3\text{O}^+\)) and hydroxide ions (\(\text{OH}^-\)).
- Use the formula:
\[
[\text{OH}^-] = \frac{K_w}{[\text{H}_3\text{O}^+]}
\]
where \(K_w\) at 25°C is \(1.0 \times 10^{-14}\).
