Question

Zapisz w postaci jonowej:

1) Ba(OH)₂+ 2HCl → BaCl₂ + 2H₂O
2) 2LiOH + H₂SO₃ → Li₂SO₃ + 2H₂O
3) NaOH + HNO₃ → NaNO₃ + H₂O
4) Mg(OH)₂+ H₂SO₃ → MgSO₃ + 2H2O

Answer 1

1. Ba²⁺ + 2OH⁻ + 2H⁺ + Cl²⁻ -> Ba²⁺ + Cl²⁻ + 2H₂O

(po skróceniu) OH⁻ + H⁺ -> H₂O

2. 2Li⁺ + 2OH⁻ + 2H⁺ + SO₃²⁻ -> 2Li⁺ + SO₃²⁻ + 2H₂O

OH⁻ + H⁺ -> H₂O

3. Na⁺ + OH⁻ + H⁺ + NO₃⁻ -> Na⁺ + NO₃⁻ +H₂O

OH⁻ + H⁺ -> H₂O

4. Mg²⁺ + 2OH⁻ + 2H⁻ + SO₃²⁻ -> Mg²⁺ + SO₃²⁻ + 2 H₂O

OH⁻ + H⁺ -> H₂O 

Answer 2

1)Ba+ +2OH- + 2H+ + 2CL- --> Ba2+ +2Cl- + 2H2O

 

2)2Li+ + 2OH- + 2H+ + SO32- --> 2Li+ + SO32- + 2H2O

 

3)Na+ + OH- + H+ + NO3- --> Na+ + NO3- + H2O

 

4)Mg2+ + 2HO- + 2H+ + SO32- --> Mg2+ + SO32- + 2H2O
