Zapisz w formie czasteczkowej , jonowej i jonowej skroconej rownania reakcji:
a)siarczan 6 sodu
b) azotan 5 wapnia
a)
H₂SO₄ + 2NaOH --> Na₂SO₄ + 2H₂O
H₂SO₄ --> 2H⁺ + (SO₄)₂⁻
2NaOH -->2Na⁺ + 2OH⁻
Na₂SO₄ --> 2Na⁺ + (SO₄)₂⁻
2H⁺ + (SO₄)₂⁻ + 2Na⁺ + 2OH⁻ --> 2Na⁺+ (SO₄)₂⁻ + 2H₂O
2H⁺ + 2OH⁻ ---> 2H₂O/:2
H⁺+ OH⁻ --> H₂O
b)
2HNO₃+Ca(OH)₂->Ca(NO₃)₂+2H₂O
2HNO₃ --> 2H⁺ + 2NO₃⁻
Ca(OH)₂ --> >Ca²⁺ + 2OH⁻
Ca(NO₃)₂ --> Ca²⁺ + 2NO₃⁻
2H⁺ + 2NO₃⁻+ Ca²⁺ + 2OH⁻ --> Ca²⁺ + 2NO₃⁻ + 2H₂O
2H⁺ + 2OH⁻ --> 2H₂O/:2
H⁺ + OH⁻ --> H₂O
