Question

State Henry's law. Calculate the solubility of CO2 in water at 298 K under
760 mm Hg.
(KH for CO2 in water at 298 K is 1.25 x 1000000 mm Hg)
​

Answer 1

Answer:

In physical chemistry, Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant.We know by Henry's Law ; p = kH * x , where x is mole fraction of the gas in the solution. Moles of gas = 608 * * 55.5 mol = 33744 * = 33.74 * mol. Therefore, solubility of CO2 in water is 33.74* mol/L.
