Question

State Henry’s law and list the conditions necessary for the validity of Henry’s law

Answer 1

Answer:

The Henry law states that

The partial pressure of the gas is directly proportional to the mole fraction.

The cdition which are valid for this law are as follow :

1)the temperature should be low.

2)the pressure should be high

3)rhe compound does not undergo any relation (dissociation or association reaction).

Answer 2

Answer:

At a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.

APPLICABILITY OF HENRY`S LAW:

#Henry's law only works if the molecules are at equilibrium.

#Henry's law does not work for gases at high pressures (e.g., N2(g) at high pressure becomes very soluble and harmful when in the blood supply).

#Henry's law does not work if there is a chemical reaction between the solute and solvent (e.g., HCl(g) reacts with water by a dissociation reaction to generate H3O+ and Cl− ions)
