State and explain Henry's law

Text Solution

Verified by Experts

Henry.s law: This law states "that the partial pressure of the gas in vapour phase is directly proporational to the mole fraction (x) of the gaseous solute in the solution at low concentrations.
`P _("solute") prop x_("solute in solution")`
`P _("solute")K _(H)x _("solute in solution")`
`x _("solute")=` mole fraction of solute in the solution
`K _(H)=` empirical constant.
`P _("solute")=` Vapour pressure of the solute (or) the partial pressure of the gas in capour state.
The value of `K _(H)` depends on the nature of the gaseous solute and slovent.
