Question
Which one of the following statements regarding Henry's law is not correct ?
Choose an option
Show full solutionCorrect option: A
Correct answer
AHigher the value of KH at a given pressure, higher is the solubility of the gas in the liquids
Step-by-step explanation
From Henry's law we know,
Pgas = KH xg
Where, Pgas = Pressure of undissolved gas
xg = Mole fraction of gas dissolved into the liquid.
KH = Henry's Carnot.
When pressure is constant then,
xg
So. when KH is high then xg or solubility of gas is lower in the liquid.
So, option (A) is wrong.
Pgas = KH xg
Where, Pgas = Pressure of undissolved gas
xg = Mole fraction of gas dissolved into the liquid.
KH = Henry's Carnot.
When pressure is constant then,
xg
So. when KH is high then xg or solubility of gas is lower in the liquid.
So, option (A) is wrong.
