What happens when dilute sulphuric acid is treated with: a. Fe? b. CaF2? |
|
Answer» a. Dilute H2SO4 reacts with Fe which is below hydrogen in the electrochemical series, with the evolution of H2. Fe (Iron) + H2SO4 (Sulphuric acid) → FeSO4 (Ferrous sulphate) + H2 (Hydrogen) b. When H2SO4 is added to calcium fluoride, hydrogen fluoride is obtained. CaF2 (Calcium fluoride) + H2SO4 (Sulphuric acid) → CaSO4 (Calcium sulphate) + 2HF (Hydrogen flurode) |
