а)
LiOH + HNO₃= LiNO₃ + H₂O
Li⁺ + OH⁻ + H⁺ + NO₃⁻ = Li⁺+NO₃⁻ + H₂O
OH⁻ +H⁺ = H₂O
б) H₂SO₄+BaCI₂= BaSO₄↓ + 2HCI
2H⁺ + SO₄²⁻+ Ba²⁺ + 2CI⁻=BaSO₄↓ +2H⁺ + 2CI⁻
SO₄²⁻+ Ba²⁺ =BaSO₄↓
в) Ca(OH)₂ +Na₂CO₃ =CaCO₃↓+2NaOH
Ca²⁺ + 2OH⁻ +2Na⁺ + CO₃²⁻= CaCO₃↓+2Na⁺ + 2OH⁻
Ca²⁺ + CO₃²⁻= CaCO₃↓
г)
Na₂CO₃ + 2HCI = 2NaCI + CO₂↑+H₂O
2Na⁺ + CO₃²⁻ + 2H⁺ + 2CI ⁻= 2Na⁺ + 2CI⁻ + CO₂↑+H₂O
CO₃²⁻ + 2H⁺ = CO₂↑+H₂O
