How do i get rid of dry ice?

Question

im planning to make a dry ice experiment for my class but i have one problem...... HOW DO I GET RID OF THE DRY ICE IN HOT WATER AFTER IM DONE WITH SHOWING IT! my teacher would kill me if it exploded or anything as crazy as that so i need to find out how to get rid of it saftley before i can do the sciense experiment.

Answer 1

Dry Ice is just solid CO2, when exposed to room temperature it sublimates into the gas form of CO2, putting it in hot water will just speed up this process your experiment sort of answers itself in this one but to avoid any problems keep the room well ventilated.

Answer 2

Just leave it in the sink but make sure no one touches it. Dry ice is frozen carbon dioxide, it would eventually sublime.

Answer 3

You can deposit it back from where you bought it...

If you cant remember, gas/ petrol stations usually have dry ice collections.

Hope this helps

good luck with your experiment!

Answer 4

by itself, it will just slowly sublimate (not melt) as the CO2 gas dissipates in the atmosphere.

Do not put it in hot water, bad idea. The water will bubble rapidly as CO2 is rapidly released, and the water will then freeze, slowing down the sublimation.

Just let it sit.

I'd put it outside if this is a small room with people in it, as excess CO2, while not dangerous, can cause rapid breathing.

Answer 5

i dont think that dry ice is dangerous

i think that you can just let it melt and then wash it down the sink with water

Answer 6

If you are not using a large amount, it will simply evaporate into the air and you will have nothing to get rid of. As for the exploding, the only explosions I'm aware of that involve dry ice are if you confine it in a small air tight area so you should be safe there too.

Answer 7

Dry ice isn't going to explode.  Just leave it in the water.  It will eventually melt.  Of course melted dry ice goes straight from solid to gas.  Just make sure that no one is handling the solid dry ice without protective gloves.  It is so cold, that it will actually give your skin a freezer burn.

Answer 8

Put it in the sink and let it melt

Answer 9

Dry ice is  solid carbon dioxide. It is commonly used as a versatile cooling agent. Dry ice sublimates, changing directly to a gas at atmospheric pressure. Its sublimation and deposition point is -78.5 °C (-109.3 °F). Its enthalpy of sublimation (ΔHsub) at -78.5 °C (-109.3 °F) is 571 kJ/kg (245.5 BTU/lb). The low temperature and direct sublimation to a gas makes dry ice a very effective coolant, since it is colder than ice and leaves no moisture as it changes state.

Answer 10

heat it up. even though its co2 just heat it up.

Answer 11

It's frozen carbon dioxide.  It's the same stuff we exhale, only colder.  It wont hurt anything.

Answer 12

Just let is sublimate. It won't do anything bad, it won't even melt, because i just goes immediately to a gas. So it doesn't matter, just leave it outside or on a table or something.
