Is carbon dioxide and water a homogeneous mixture?
Answer: Carbon dioxide gas dissolved in water a homogenous mixture. Explanation: Carbon dioxide reacts with water to form carbonic acid which is a compound.
Why carbon dioxide is a homogeneous mixture?
Sometimes gases can be dissolved in liquids. For example, carbonated drinks have carbon dioxide dissolved in water, making a homogeneous mixture. Water is a chemical substance that contains only molecules made of two hydrogen atoms and one oxygen atom, so it’s a compound.

How do you describe the solution of carbon dioxide and water?
The solution of carbon dioxide in water is called carbonic acid.
Can water and carbon dioxide form a solution?
Remind students that water and carbon dioxide react to form carbonic acid. A hydrogen atom from the carbonic acid gets into the water as a hydrogen ion (H+). Extra hydrogen ions in the water also makes the water more acidic.
Is carbon dioxide a pure substance homogeneous or heterogeneous?
Because carbon dioxide is dissolved in water, we can infer from the behavior of salt crystals dissolved in water that carbon dioxide dissolved in water is (also) a homogeneous mixture.
What happens when carbon dioxide in exhaled air mixed with water?
When carbon dioxide reacts with water a weak acid is formed. Carbon dioxide present in exhaled air is blown into a flask containing an indicator sensitive to small changes of pH in the appropriate region of the pH scale, and the consequent colour changes observed and recorded.
Why is carbon dioxide soluble in water?
CO2 is soluble because water molecules are attracted to these polar areas. The bond between carbon and oxygen is not as polar as the bond between hydrogen and oxygen, but it is polar enough that carbon dioxide can dissolve in water.
Why water is a homogeneous?
Water – another example of homogeneous mixture; all but the purest water contains dissolved minerals and gases; These are dissolved throughout the water, so the mixture presents in the same phase and is homogeneous.
Is carbon di oxide and water a homogeneous or heterogeneous mixture?
A solution of carbon di oxide and water will result in the formation of Carbonic Acid. Since a chemical compound is formed here, It will surely a homogeneous mixture as all compounds are homogeneous in nature.
What is an example of a homogeneous solution?
A homogeneous solution tends to be identical, no matter how you sample it. Homogeneous mixtures are sources of water, saline solution, some alloys, and bitumen. Sand, oil and water, and chicken noodle soup are examples of heterogeneous mixtures.
Why is a solution a mixture?
A solution is a form of mixture where one compound is dissolved in another. Water is a very good solvent, many compounds will readily dissolve in water to produce a solution. Once dissolved these compounds are usually evenly distributed in the solution, resulting in a homogeneous solution (mixture). It’s not.
Is carbon dioxide a mixture or compound?
No, carbon dioxide is a single substance (CO2). As Ted Krapkat has already noted, if you are talking about pure carbon dioxide, then it is a molecular compound and is not a mixture of gases.
