What is the colour of liquid carbon dioxide?

What is the colour and odour of gaseous, liquid and solid carbon dioxide?What is the colour of liquid carbon dioxide?
Carbon dioxide gas is colorless. At low concentrations, the carbon dioxide gas is odorless. At higher concentrations it has a sharp, acidic odor. It will act as an asphyxiant and an irritant.

Liquid carbon dioxide forms only at pressures above 5.1 atm; Thus at atmospheric pressure liquid carbon dioxide does not exist, so it's odor would be impossible to determine, however, the odor would result from gas evaporating from the liquid CO2, so presumably the odor would be that of gaseous CO2. Liquid carbon dioxide is also colorless.

Solid carbon dioxide ';dry ice'; is usually white due to the small crystals of carbon dioxide interspersed with air voids.


(i.e. just like snow formed from water). If you compressed a piece of dry ice it will become translucent. Dry ice would give off carbon dioxide gas, which would be odorless in low concentrations but have a sharp, acidic odor at high concentrations.

CO2 is virtually colorless, and there is no actual liquid form of it.





In gaseous state, it is colorless. You cannot see it. Can you see oxygen? No





In solid state [dry ice] it is WHITE.


To make dry ice they must freeze CO2[gas] at an EXTREMELY COLD Temperature, so it goes directly from a gas to a solid. When in solid form, you can actually see the dry ice sublimating [solid-%26gt;gas] and giving off a white or colorless vapor. If you sniff it, you will become faint because it is RAW CO2, which is bad for your lungs.
gaseous CO2 odorless and colorless


liquid CO2 odorless and colorless


Solid CO2 odorless and probably colorless but it appears as opaque or even white, usually due to surface ice.
Liquid carbon dioxide doesn't exist under normal conditions. You have to up the pressure for that. I don't know what color it has.





Solid carbon dioxide looks like white solid, basically like ice. It is dry ice.





Any carbon dioxide would smell like gaseous carbon dioxide... i.e. it would not smell at all.
