Write an equation that explains the conductivity of CO2(aq, saturated)

CO2 + H2O ==> H2CO3

H2CO3 ==> H^+ + HCO3^-
HCO3^- ==> H^+ + CO3^=
The last equation takes place only to a very small amount

The equation that explains the conductivity of CO2 (aq, saturated) is:

CO2 (aq) ⇌ CO2 (g) + H2O

The equation that explains the conductivity of CO2(aq, saturated) can be determined based on the principle of ionization of carbon dioxide in water.

To write the equation, we need to consider the dissociation of CO2 in water, which results in the formation of ions. In water, CO2 reacts to form carbonic acid (H2CO3), which then partially dissociates into positively charged hydrogen ions (H+) and negatively charged bicarbonate ions (HCO3-).

The equation can be written as follows:

CO2(aq) + H2O(l) ⇌ H2CO3(aq) ⇌ H+(aq) + HCO3-(aq)

In this equation, CO2(aq) represents the dissolved carbon dioxide in water, H2O(l) denotes water, H2CO3(aq) is carbonic acid, H+ represents hydrogen ions, and HCO3- denotes bicarbonate ions.

The conductivity of CO2(aq, saturated) is influenced by the concentration of ions present in the solution. In this case, it is mainly determined by the concentration of hydrogen ions (H+) and bicarbonate ions (HCO3-), as they are the main charge carriers.

By measuring the conductivity of a saturated solution of CO2(aq), you can determine the degree of ionization and hence the conductivity of the solution. Conductivity measurements are typically made using a conductometer, an instrument specifically designed to measure the electrical conductivity of a solution.

To summarize, the equation explaining the conductivity of CO2(aq, saturated) is:
CO2(aq) + H2O(l) ⇌ H2CO3(aq) ⇌ H+(aq) + HCO3-(aq)
To measure the conductivity, use a conductometer to determine the concentration of hydrogen ions (H+) and bicarbonate ions (HCO3-) in the solution.
