Question

10 examples for double displacement reaction

Answer 1

Answer:

Double displacement reactions occur when a part of two ionic compounds are exchanged and make two new components. The pattern of a double displacement reaction is like this.

Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate and exchange of ions takes place.

Answer 2

Answer:

"A double displacement reaction is one in which the exchange of ions takes place. The salts which are soluble in water are designated by the symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas."

Explanation:

Examples of Double Displacement Reaction:

(1).  BaCl₂ + Na₂SO₄ ⇨ BaSO₄ + 2NaCl

(2). Na₂SO₄ + BaCl₂ ⇨ BaSO₄ + 2NaCl  

(3).  AgNO₃ + NaCl ⇨ AgCl + NaNO₃

(4).  2KI + Pb(NO₃)₂ ⇨ PbI₂(s) + 2KNO₃

(5).  AgNO₃ +  NaCl ⇨ AgCl(s) + NaNO₃    

(6).  BaCl₂ + Na₂SO₄ ⇨ BaSO₄(s) + 2NaCl

(7).  Pb(NO₃)₂ + 2KI ⇨ PbI₂(s) + 2KNO₃

(8).  2KBr+BaI₂ ⇨ 2KI+BaBr₂

(9).  Al₂(SO₄)₃ + 6NH₄OH ⇨ 2Al(OH)₃(s) + 3(NH₄)2SO₄

(10).  CuSO₄(aq) + H₂S(g) ⇨ CuS(g) + H₂SO₄(aq)
