When dilute sulphuric acid is added to pieces of iron sulphide, hydrogen sulphide gas is produced and soluble ferrous sulphate is formed. The type of chemical reaction involved is A. decomposition reaction B. combination reaction C. displacement reaction D. double displacement reaction |

Answer» Dilute sulphuric acid: dil. H2SO4 Iron sulphide: FeS Hydrogen sulphide: H2S Ferrous sulphate: FeSO4 The reaction involved can be written as: FeS + H2SO4→ FeSO4 + H2S We can see that there is the exchange of SO42- and S2- ions in the reactants. Thus it is a double displacement reaction. |
