1. H2S, a toxic gas with rotten egg smell is used for the qualitative analysis. if the solubility of H2S in water at STP is 0.195m, calculate henry's constant.
  2. Henry's law constant for CO2 in water is 1.67*10 raise to the power 8 Pa at 298K. Calculate the quantity of CO2 in 500 mL of soda water when packed under 2.5 atm CO2 pressure at 298 K.

Expert Answer:

1. The solubility of H2S gas = 0.195 m = 0.195 moles of H2S is dissolved in 1 kg of water (solvent).
Thus, the Henry's constant = 282 bar
 
 
2. Please post second question as the separate query.
