Answer
(a) Sulphurous acid
(b) Carbon dioxide gas
(c) Liquid E is Ethanol [C2H5OH]
C2H5OH + H2SO4 (conc.) ⟶ C2H4 + H2O
(d) Hydrogen sulphide gas (H2S)
H2S + H2SO4 [conc.] ⟶ S + SO2 + 2H2O
(e) Dilute sulphuric acid.
(f) Hydrogen sulphide (H2S)
(g) Dilute sulphuric acid.
BaCl2 + H2SO4 (dil) ⟶ 2HCl + BaSO4 ↓ [white ppt. formed]
(h) Conc. sulphuric acid
(i) Dilute sulphuric acid
