5.Classify the following salts and identify the correct classification for each along with the appropriate chemical equation for their formation: i) Sodium hydrogen sulphate (NaHSO₄) ii) Basic lead chloride (Pb(OH)Cl) iii) Potash alum (K₂SO₄·Al₂(SO₄)₃·24H₂O) Which of the following correctly matches the classification and formation equation for all three salts?
- A.i) Acid salt: H₂SO₄ + NaOH → NaHSO₄ + H₂O; ii) Basic salt: Pb(OH)₂ + HCl → Pb(OH)Cl + H₂O; iii) Double salt: Crystallization of K₂SO₄ and Al₂(SO₄)₃
- B.i) Normal salt: H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O; ii) Acid salt: PbO + 2HCl → PbCl₂ + H₂O; iii) Complex salt: K₂SO₄·Al₂(SO₄)₃·24H₂O formed from KAl(SO₄)₂
- C.i) Basic salt: NaOH + H₂SO₄ → NaHSO₄ + H₂O; ii) Normal salt: Pb(OH)₂ + 2HCl → PbCl₂ + 2H₂O; iii) Mixed salt: K₂SO₄ and Al₂(SO₄)₃ crystallized separately
- D.i) Acid salt: Na + H₂SO₄ → NaHSO₄ + H₂; ii) Basic salt: PbCl₂ + NaOH → Pb(OH)Cl + NaCl; iii) Double salt: Formed from K₂SO₄·Al₂(SO₄)₃ without water
