 | | It is prepared by reacting calcium oxide (lime) with water, a process called slaking, and is also known as hydrated lime or slaked lime. |
 | | Limewater is a clear, saturated water solution of calcium hydroxide. |
 | | Because calcium hydroxide readily reacts with carbon dioxide, CO, to form calcium carbonate, a mixture of gases can be tested for the presence of CO by shaking it with limewater in a clear container; if CO is present, a cloudy calcium carbonate precipitate will form. |
