Question

what is henry constant...​

Answer 1

$\textsf{\underline{\Large {Henry's Constant}}}$ :

$\textsf{\underline{Henry's Law}}$ : Henry's Law states that " the mass of a gas dissolved in a given mass of a solvent at any temperature is directly proportional to the pressure of the gas above the solvent."

$\boxed{\mathsf{m\:{\propto{\:p}}}}$

Also the partial pressure of the gas in vapour phase is directly proportional to the mole fraction of the gas in the solution.

$\boxed{\mathsf{p\:{\propto{\chi}}}}$

On removing the proportionality sign, we insert a constant which is known as $\textsf{\underline {Henry's Constant}}$.

$\boxed{\mathsf{p\:=\:{K_{H}{\chi}}}}$

⚫p = Partial Pressure

⚫$\mathsf{\chi}$ = Mole Fraction of the gas

➡️ $\mathsf{K_H \:=\: Henry's \:Constant}$
