State Henry's law .

Text Solution

Verified by Experts

The correct Answer is:
According to him," the partial pressure of the gas in vapour phase (vapour pressure of the solute) is directle proportional to the mole fraction (x) of the gaseous solute in the solution at low concentrations" is statement is known as Henry's law.
Henry's law can be expressed as,
`P_("solute")propX_("solute in solution")`
`P_("solute")=K_(H^(X_("solute in solution")))`
Here, `P_("solute") ` represents the partial pressure of the gas in vapour state which is commonly called as vapour pressure.
