Which pH range corresponds to a strong base?

Explanation:
On the pH scale, bases raise the pH above 7, and the strength of a base depends on how completely it dissociates in water and how many hydroxide ions it produces. A strong base dissociates almost completely, flooding the solution with OH− ions and pushing the pH toward the very top end of the scale. That top end corresponds to the strongest basic solutions. So the pH range at the high end is the one that identifies a strong base. A basic range that sits lower on the scale is still basic but weaker, while any range below 7 is acidic.
