Is Sr(OH)₂ Classified as an Acid, a Base, or a Salt? Explain.

Sr(OH)2, or Strontium Hydroxide, is classified as a base. This classification is based on its chemical structure and its behavior in an aqueous solution.

Strontium Hydroxide consists of strontium ions (Sr2+) and hydroxide ions (OH). When it dissolves in water, it dissociates into these ions, releasing hydroxide ions into the solution. Hydroxide ions are characteristic of bases, as they can accept protons (H+) from acids.

Moreover, according to the Brønsted-Lowry theory, a substance that increases the concentration of hydroxide ions in solution is considered a base. Since Sr(OH)2 meets this criterion, it is appropriately classified as a strong base.

In summary, Sr(OH)2 is a base because it produces hydroxide ions in solution and can neutralize acids, which is the defining behavior of a base.
