Dry ice is a cool matter, don’t you agree?
Dry ice, as the name suggests, is a solid thing that has a very low temperature and appears dry, which means it’s not dripping into a mess like the regular ice. But, what kind of matter is this actually?
Is dry ice an element, compound, or mixture?
Dry ice is a compound with a chemical formula of CO2. Yes, dry ice is the solid form of Carbon Dioxide (CO2). CO2 consists of carbon atom and oxygen atoms that bond chemically in a definite ratio. It means that dry ice (solid CO2) is a compound. It’s neither an element nor a mixture.
Wow, how cool is that?!

What Is Dry Ice?
Dry ice is the solid form of carbon dioxide (CO2). It’s called dry ice because it’s so cool and it can be used for cooling agent but it’s ‘dry’ because when the temperature rises up, it doesn’t convert into liquid to cause a mess; it sublimes (converts directly into a gas).
Dry ice happens when liquified carbon dioxide injected into a tank and then frozen and compressed.
Is Dry Ice An Element?
No, dry ice is not an element. Dry ice is the solid form of Carbon Dioxide, which consist of two different atoms i.e. carbon and oxygens. Those atoms bonds chemically in a consistently certain ratio. It means that dry ice (CO2) is a compound, not an element.
In science, an element is a very simple matter that consists of only the same kind of atom. There are 118 elements in the periodic table.
Each of those elements has special features. Elements cannot be broken down into something else. They are themselves.
Dry ice does not fulfill the criteria of being an element since it consist of more than 1 kind of atom.
Is Dry Ice A Compound or Mixture?
Dry ice (CO2) is a compound, not a mixture. This is because dry ice consists of carbon atom and oxygen atoms combine together chemically in a definite ratio.
Compound and mixture both consists of two or more substances. But they are different.
A compound always need a certain ratio of composition. The same kind of compound always has consistent ratio of constituents.
On the contrary, a mixture doesn’t need a fixed ratio of composition. The composition can vary in ratio.
Dry ice consist of carbon and oxygen. The molecule of dry ice (CO2) always has 1 carbon atom and 2 oxygen atoms, it’s consistent. This means that dry ice (CO2) is a compound, not a mixture.
Is Dry Ice Carbon Dioxide?
Yes, dry ice is carbon dioxide in a solid form.
In room temperature and normal pressure, carbon dioxide is a colorless gas. But when it’s liquified, frozen, and compressed, it can turn into the solid form that looks like a white ice.
Is Dry Ice Cold?
Yes, dry ice is super cold. In fact, to make a dry ice, you need to put the liquified carbon dioxide into a temperature of -109.3 Fahrenheit.
Is Dry Ice Dangerous?
Yes, it can be dangerous if not used and stored correctly. Touching dry ice can cause frostbite as it’s extremely cold. When sealed in an airtight container and then placed inside a cooler, it can explode. When it’s healed inside a hypo-ventilated space, it can make someone unconcious.
