The Total solution for NCERT class 6-12
H2S, a toxic gas withrotten egg like smell, is used for the qualitative analysis. If the solubilityof H2S in water at STP is 0.195 m, calculate Henry’s law constant.
It is given that thesolubility of H2S in water at STP is 0.195 m, i.e., 0.195 mol of H2Sis dissolved in 1000 g of water.
= 55.56 mol
= 0.0035
At STP, pressure (p) =0.987 bar
According to Henry’s law:
p = KHx
= 282 bar
