Why CO2 will dissolve in water? thx

In summary, CO2, being an acidic oxide, can react with water to form a salt species and can "dissolve" in water due to its partial pressure above the liquid's surface. Although CO2 has a net dipole moment of zero, water can still be attracted to it through other means. This explains why CO2, despite being non-polar, can dissolve in water, a polar solvent.

As title, CO2 is non-polar, why it can dissolve in water which is a polarized slovent?

For one CO2 is an acidic oxide, it reacts with water to produce a salt species. Also, "dissolve" is not equated with solubility. As long as a gas, such as CO2, has a partial pressure above water, it will run into the surface of the liquid (such as water) and in a sense dissolve. CO2 has a net dipole moment of zero, however water can still be attracted to it through other means than dipole-dipole interactions.

Thanks for the reply, I was confused because of the like dissolves like theory.
 

FAQ: Why CO2 will dissolve in water? thx

1. Why does CO2 dissolve in water?

CO2 is a polar molecule, meaning it has both a positive and negative charge. Water molecules are also polar, and therefore they are attracted to the CO2 molecules. This attraction allows the CO2 to dissolve in water.

2. How does CO2 dissolve in water?

CO2 dissolves in water through a process called dissolution. The polar nature of both CO2 and water allows them to bond with each other, forming a solution. The CO2 molecules are surrounded by water molecules, which breaks them apart and allows them to dissolve.

3. What factors affect the solubility of CO2 in water?

The solubility of CO2 in water is affected by several factors, including temperature, pressure, and the presence of other substances. Generally, as temperature and pressure increase, the solubility of CO2 in water decreases. Other substances, such as salts, can also affect the solubility of CO2 in water.

4. Why is it important for CO2 to dissolve in water?

CO2 dissolving in water is important for several reasons. It helps regulate the pH of water, making it less acidic. It also plays a crucial role in the carbon cycle, as it is necessary for aquatic plants to perform photosynthesis. Additionally, the dissolved CO2 in water is essential for the survival of many aquatic organisms.

5. Can CO2 dissolve in any type of water?

Yes, CO2 can dissolve in any type of water, including freshwater, saltwater, and even distilled water. However, the solubility may vary depending on the type of water and its temperature and pressure. For example, cold water can hold more dissolved CO2 than warm water, and saltwater can hold more CO2 than freshwater.
