CaO (lime) is the cheapest and most widely used commercial base. It is commonly used in industries such as agriculture, water treatment, metallurgy, and construction. NH₃ (ammonia) and NaOH (lye) are also commonly used bases, but they are more expensive than CaO. Na₂O (sodium oxide) is not commonly used as a base due to its high reactivity and potential safety hazards.
