Question

50 points - Please list the Properties of Carbon Dioxide.

Answer 1

Answer:

• carbon dioxide is a colorless gas with a faint acidic taste and smell.
• It is about one and a half times heavier than air.
• it is fairly soluble in water and its solubility greatly increases with increase in pressure.

Answer 2

Answer:

MARK ME AS BRAINLIEST...

Explanation:

Properties of CO2

Co2 Molecule - Properties of Cryogenic CO2

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

Uses of CO2

It is used to neutralize alkaline water.

Carbon dioxide is used as an additive to oxygen for medical use as a respiration stimulant

Liquid Frozen Carbon Dioxide (Co2) is a good solvent for many organic compounds.

Liquid Frozen Carbon Dioxide (Co2) is used as a propellant in aerosol cans, it replaces more environmentally troublesome alternatives

It is used for refrigeration and cooling.

It is used as an inert gas in chemical processes, in the storage of carbon powder and in fire extinguishers.

It is used in solid as well as in liquid form

It is used in metal industry in the formation of casting molds to enhance their hardness

Carbon dioxide gas is used to carbonate soft drinks, beers and wine and to prevent fungal and bacterial growth.

Large quantities are used as a raw material in the chemical process industry, especially for methanol and urea production.

It is used in oil wells for oil extraction and maintain pressure within a formation

Liquid or solid carbon dioxide is used for quick freezing, surface freezing, chilling and refrigeration in the transport of foods etc.
