When students and chemistry enthusiasts ask, is Ca(OH)2 a strong base, the answer depends on understanding the difference between chemical strength and physical solubility. Consider this: calcium hydroxide, commonly known as slaked lime or hydrated lime, is widely classified as a strong base because every molecule that dissolves in water dissociates completely into calcium ions and hydroxide ions. On the flip side, calcium hydroxide is only sparingly soluble, which means a saturated solution contains relatively few dissolved molecules compared with highly soluble bases like sodium hydroxide. This unique combination—complete dissociation of a limited amount of solute—often leads to confusion in classrooms and laboratories alike.
