**Solubility Product Problem**

Assume the solubility product of \( \text{Mg(OH)}_2 \) is \( 1.3 \times 10^{-11} \) at a certain temperature. What minimum OH\(^-\) concentration must be attained (for example, by adding NaOH) to decrease the Mg\(^{2+}\) concentration in a solution of \( \text{Mg(NO}_3\text{)}_2 \) to less than \( 1.2 \times 10^{-10} \) M.

\[ \boxed{\phantom{xxx}} \times 10^{\boxed{\phantom{xxx}}} \text{ M} \]

*(Enter your answer in scientific notation.)*

---

**Note:** This problem asks you to calculate the necessary hydroxide ion concentration to achieve a specific magnesium ion concentration in solution via the solubility product concept.
