Question

14. Ca(OH)2 +CO2 → CaCO3 + H20. In this reaction shiny finish to walls is due
+
to
A) Ca(OH)2
B) CaCO3
C) CO2
D) HO​

Answer 1

Answer:

CaCO3

Explanation:

White washing involves Calcium hydroxide and after two to three days calcium carbonate is formed and gives the shiny finish to the walls.

Answer 2

AnswEr :

In the mentioned reaction, shiny finish to walls happens due to Calcium Carbonate [CaCO3] .

So, the correct answer is option (B)

$\dag \: { \LARGE{ \boxed{ \sf{ \purple{CaCO_3}}}}}$

Calcium hydroxide is used to white wash the walls. It reacts with the carbon dioxide present in air to form thin layer of calcium carbonate [CaCo3] on the walls.

Thus, It gives a shiny finish to the walls .

The reaction goes as well,

$\boldsymbol{CaO + H_2O \longrightarrow \: Ca(OH)_2}$

$\boldsymbol{Ca(OH)_2 + CO_2 \longrightarrow CaCO_3}$
