H2S cannot be dried by using concentrated H2SO4-explain why with balanced equations.
H2S cannot be dried by using concentrated H2SO4 because H2SO4 reacts with H2S to form sulfur and water, which can lead to the formation of a highly explosive mixture of sulfur dioxide and hydrogen sulfide. The balanced chemical equation for this reaction is:
H2SO4 + H2S → 2H2O + S
As seen in the equation, the reaction between H2SO4 and H2S leads to the formation of water and elemental sulfur. Therefore, H2SO4 cannot be used to dry H2S gas as it will not remove moisture and can lead to the formation of a hazardous mixture.
