(a) Solution of a substance 'X' is used for testing carbon dioxide. Write the equation of the reaction of
'X' with carbon dioxide.
(b) How is obtained ? Write chemical equation.

1. X=Ca(OH)2-Calcium Hydroxide
equation. = CO2 + Ca(OH)2 =>CaCO3 ( Calcium Carbonate)
2.When CaO is reacted with water then Calcium Hydroxide is formed.
equation= CaO + H2 => Ca(OH)2
3.Substance X is Solution of CaO not CaO because Only CaO solution reacts with CO2 to form Ca(CO)3 i.e. precipitate (white in colour used to determine the presence of CO2)
equation. = CO2 + Ca(OH)2 =>CaCO3 ( Calcium Carbonate)

abinash055otv0s8:
but bri the question is solution of substance no term such as solution of calcium hydroxide exists
bro*
ur answers is like, name the substance whos solution is a elctrolyte then the ans is sodiumchloride solution not sodium chloride
hey bro here i mean that CaO solution​ = Cao + H2O => Ca(OH)2 which only helps in determining CO2.... HOPE U UNDERSTAND THAT
so bro the substance is cao and its solution is caoh2 the x is cao
yep
