The term that describes Ca(OH)2 is strong base. Calcium hydroxide, or Ca(OH)2, is a compound that dissociates completely in water to produce hydroxide ions (OH-). This complete dissociation indicates that it is a strong base, as strong bases are characterized by their ability to fully ionize in solution. Calcium hydroxide is commonly used in various applications, including agriculture for soil treatment, in construction for making mortar, and as a pH regulator in water treatment processes. Understanding the properties of bases and their behavior in solution is crucial in chemistry, particularly in acid-base reactions.
