Question

what are the property of CO2

Answer 1

Physical properties of CO2 :-
Carbon dioxide is a colorless & odorless gas. It is soluble in water, ethanol , acetone and has the following properties :

Melting Point : -55.6 degC

Boiling Point : -78.5 degC

Density : 1.977

 

Chemical properties of CO2 :-

Carbon dioxide is a linear covalent molecule.

Carbon dioxide is an acidic oxide and reacts with water to give carbonic acid.

CO2 + H2O ==> H2CO3

Carbon dioxide reacts with alkalis to give carbonates and bicarbonates.

CO2 + NaOH ==> NaHCO3 (Sodium BiCarbonate )

NaHCO3 + NaOH ==> Na2CO3 (Sodium Carbonate) + H2O
