January 29, A. I totally agree with Geoff.

However, you may also wish to investigate the concept of pCO2, which would be the CO2 equivalent of pH. I would only like to add that your statement "this information will be very helpful to me if answered as soon as possible" is also not so true. At least not for a student.

The helpful information is the one that you find yourself, discuss and understand. Not someone else's passed on you.

## Carbonic acid

Hope you read this and understand it. CO2 is basically acidic in nature; when you tend to neutralize a basic solution so the range of pH for carbon dioxide would be probably Haris Tanauli - Karachi, Pakistan March 12, A.

An aqueous solution of Carbon dioxide is mildly acidic. Its pH can't be between It has to be slightly more than 6.

Okay as a student I know what examiners and teachers want to see. CO2 is slightly acidic and has a pH of 2, although is accepted but 2 is the answer. I know it sounds absurd but that is it.

However, carbonic acid only ever exists in solution in equilibrium with carbon dioxide, and so the concentration of H2CO3 is much lower than the concentration of CO2, reducing the measured acidity. The equation may be rewritten as follows c. This figure is quoted as the dissociation constant of carbonic acid, although this is ambiguous: Role of carbonic acid in blood Carbonic acid plays a very important role in mammalian blood.

### pH level of CO2 / Carbon Dioxide

It is an intermediate during the transfer of carbon dioxide from the lungs to the blood and vice versa. The conversion of carbon dioxide into carbonic acid is catalyzed by an enzyme carbonic anhydrasewhich enhances the reaction rate by a factor of nearly a billion. This dissociation is an equilibrium reaction and it helps control the pH level of blood. They did so by exposing a frozen mixture of water and carbon dioxide to high-energy radiation, and then warming to remove the excess water.

The carbonic acid that remained was characterized by infrared spectroscopy. The ability to produce carbonic acid by irradiating a solid mixture of H2O and CO2 has led to suggestions that H2CO3 might be found in outer space, where frozen ices of H2O and CO2 are common, as are cosmic rays and ultraviolet light, to help them react.
