Directions: In the following questions, a statement of assertion (A) ...
Assertion: After white washing the walls, a shiny white finish on walls is obtained after two to three days.
Reason: Calcium Oxide reacts with Carbon dioxide to form Calcium Hydrogen Carbonate which gives shiny white finish.
The correct answer is option 'C', which states that the assertion (A) is true but the reason (R) is false.
Explanation:
White washing is a process of applying a mixture of lime and water to the walls. It is commonly used to give a fresh and clean appearance to the walls. However, the reason provided for the shiny white finish is incorrect.
Calcium Oxide (CaO) is also known as quicklime or burnt lime. When it reacts with Carbon dioxide (CO2) from the air, it forms Calcium Carbonate (CaCO3), which is a white solid. This reaction is known as carbonation. However, Calcium Hydrogen Carbonate (Ca(HCO3)2) is not formed during this reaction.
The correct chemical equation for the reaction between Calcium Oxide and Carbon dioxide is as follows:
CaO + CO2 → CaCO3
Calcium Carbonate is responsible for the white color of the walls after white washing. It forms a layer on the surface of the walls, giving them a shiny white finish. This layer is formed gradually over time as the carbonation reaction takes place. It may take a few days for the walls to achieve the desired shiny white appearance.
In conclusion, the assertion is true as white washing does result in a shiny white finish on walls. However, the reason provided is false as Calcium Hydrogen Carbonate is not formed during the reaction. The correct reason is the formation of Calcium Carbonate through the carbonation reaction between Calcium Oxide and Carbon dioxide.
Reason: Calcium Oxide reacts with Carbon dioxide to form Calcium Hydrogen Carbonate which gives shiny white finish.
The correct answer is option 'C', which states that the assertion (A) is true but the reason (R) is false.
