Compound ''A'' when dissolved in water give compound ''B'' which is us

1.	Compound ''A'' when dissolved in water give compound ''B'' which is used in white-washing. ''B'' reacts with CO2 to form a white precipitate of compound ''C'' . Identify the compound ''A'' , ''B'' , ''C'' . Also write the equation involved.anyone please answer it urgently......
Answer» Compound A reacts with water to form a compound B that is used in WHITE-WASHING. Since Ca(OH)₂ is used in white washing, *Compound A + H₂O (L) → Ca(OH)₂ (aq)* Hence Compound A can be CaO called “Quick Lime”. ______________________________ Now, Compound B reacts with CO₂ to have compound C which is white PRECIPITATE. *Ca(OH)₂ + CO₂ → CaCO₃ + H₂O* We also know that CaCO₃ is a white precipitate, hence Compound C is CaCO₃ ______________________________ Compound A : CaO Compound B : Ca(OH)₂ Compound C : CaCO₃

Answer»

Compound A reacts with water to form a compound B that is used in WHITE-WASHING.

Since Ca(OH)₂ is used in white washing,

Hence Compound A can be CaO called “Quick Lime”.

______________________________

Now, Compound B reacts with CO₂ to have compound C which is white PRECIPITATE.

We also know that CaCO₃ is a white precipitate, hence Compound C is CaCO₃
