Eh2S toxic gas with rotten egg smell is used to the quality analysis the solubility of H2S is water at STP is 0.195 calculate Henry law constant

Posted by Bhoomi Lokwani 6 years, 8 months ago

CBSE > Class 12 > Chemistry

1 answers

Sia ? 6 years, 8 months ago

Solubility of H₂S gas = 0.195 m
= 0.195 mole in 1 Kg of the solvent (water)
1 Kg of the solvent (water ) = 1000 g
{tex}= \frac{{1000g}}{{18\,g\,mo{l^{ - 1}}}}{/tex} = 55.55 moles
Mole fraction of H₂S gas in the solution (x) {tex} = \frac{{0.195}}{{0.195 + 55.55}}{/tex}
{tex}= \frac{{0.195}}{{55.745}}{/tex}= 0.0035
Pressure at STP = 0.987 bar
Applying Henry's law
{tex}P_{H_2S}=K_H\times X_{H_2S}{/tex}
{tex}K_H=\frac{P_{H_2S}}{X_{H_2S}}{/tex}
{tex}= \frac{{0.987\,bar}}{{0.0035}}{/tex}
= 282 bar
