What is a characteristic of strong bases?

A characteristic of strong bases is that they fully dissociate in solution. In the context of chemistry, strong bases are commonly defined as substances that completely ionize in water, producing a high concentration of hydroxide ions (OH⁻). This complete dissociation distinguishes them from weak bases, which only partially dissociate and establish an equilibrium in solution.

For example, sodium hydroxide (NaOH) is a typical strong base that, when dissolved in water, separates completely into sodium ions (Na⁺) and hydroxide ions (OH⁻). This behavior contributes to a significant increase in the pH of the solution, making it very basic.

The other options do not accurately describe the behavior of strong bases. Partial dissociation describes weak bases, while strong bases are characterized by their complete dissociation. Additionally, the statement that strong bases do not dissolve in water is misleading, as strong bases are soluble and their solubility is essential for their function. Finally, strong bases are not acidic; they are characterized by their ability to raise the pH, making them basic rather than acidic.
