Question

Determine the solubility of co2 in soda water at 25°c if the pressure of co2 is 5.6 atm. the henry's law constant for carbon dioxide in water at this temperature is 3.4 × 10-2 m/atm.

Answer 1

Answer : The solubility of
`CO_2` is, 0.19 mole/L

Explanation :

The formula used for henry's law is:

`S_(CO_2)=k_H* p_(CO_2)`

where,

`S_(CO_2)` = solubility of
`CO_2` = ?

`p_(CO_2)` = partial pressure of
`CO_2` = 5.6 atm

`k_H` = Henry's law constant =
`3.4* 10^(-2)m/atm`

Now put all the given values in the above formula, we get:

`S_(CO_2)=(3.4* 10^(-2)m/atm)* (5.6atm)`

`S_(CO_2)=0.19mole/L`

Therefore, the solubility of
`CO_2` is, 0.19 mole/L
