State two chemical properties each with equations of a solution containing

(i) H⁺ ions

(ii) OH^- ions

(i) Chemical properties of a solution containing H⁺ (acids) are as follows —

1. Neutralization — acids neutralizes base to give salt and water only.
   Example : CuO + H₂SO₄ ⟶ CuSO₄ + H₂O
2. Reaction with active metals — Acids react with active metals [e.g., Mg, Al, Zn, Fe] to liberate hydrogen.
   Example : Zn + 2HCl ⟶ ZnCl₂ + H₂

(ii) Chemical properties of a solution containing OH^- (bases/alkalis) are as follows —

1. Neutralization — Alkalis neutralize acids to form salt and water.
   Example :
   Ca(OH)₂ + 2HCl ⟶ CaCl₂ + 2H₂O
2. Reaction with metallic salt — Alkalis react with certain matallic salt solutions to precipitate insoluble hydroxide.
   Example :
   FeCl₃ + 3NaOH ⟶ 3NaCl + Fe(OH)₃ ↓ red brown ppt.
