Question

Write Equation of Acid with:

(i.)metallic hydrogen sulphide

(ii.)metallic hydrogen sulphite

(iii.)a metal higher in metal activity series than hydrogen

Answer 1

i) Reaction of metal hydrogen sulphide with acid
For eg :
Sodium hydrogen sulphide with Hydrochloric acid

NaHS + HCl → NaCl + H₂S


​ii) Metallic hydrogen sulphite with acid :
For eg :
Sodium hydrogen sulphite with HCl

NaHSO₃ + HCl ​→ SO₂ + H₂O + NaCl

iii) Metal higher in activity series than Hydrogen (For eg : Pb, Sn, Fe, Al, Mg , Ca etc.)

Lead is above hydrogen in activity series
Pb + H₂SO₄ ​→ PbSO₄ + H₂
