Hint: Quicklime is produced by heating crushed limestone to around 1,100 degrees Celsius in a shaft furnace or rotary kiln. The heating of limestone releases carbon dioxide, leaving calcium oxide.
Complete step by step solution: Let us first perform a detailed analysis of the physical and chemical properties of Quicklime before answering this question.
Quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term "lime" connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate. By contrast, quicklime specifically applies to the single chemical compound calcium oxide. Calcium oxide that survives processing without reacting in building products such as cement is called free lime.
For additional context, let us now look at the reaction of the phenomenon given in the hint.
Now, let us analyse the properties of as a compound.
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula . It is a colourless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water. Calcium hydroxide is used in many applications, including food preparation, where it has been identified as E number E526. Limewater is the common name for a saturated solution of calcium hydroxide.
Since, there is a clear difference between the compound Quicklime and , therefore the answer to this question is (2) false.
Note: The key part to answer this question requires a thorough knowledge of the properties and compounds of alkali earth metals. A very common mistake made in answering this question is the confusion between quicklime and slaked lime, be very careful to not make the same.
