Na₂CO₃ + 2HNO₃ =2NaNO₃ + CO₂↑ + H₂O

2Na⁺ + CO₃²⁻ + 2H⁺ + 2NO₃⁻ = 2Na⁺ + 2NO₃⁻ + CO₂↑ + H₂O

CO₃²⁻ + 2H⁺  =  CO₂↑ + H₂O

CuCI₂ + 2KOH=Cu(OH)₂↓ + 2KCI

Cu²⁺ + 2CI⁻ + 2K⁺ + 2OH⁻  = Cu(OH)₂↓ + 2K⁺ + 2CI⁻

Cu²⁺  2OH⁻  = Cu(OH)₂↓

2NaOH + H₂SO₄=Na₂SO₄ + 2H₂O

2Na⁺ + 2OH⁻ + 2H⁺ + SO₄²⁻ = 2

Na⁺ + SO₄²⁻ + 2H₂O

2OH⁻ + 2H⁺  =  2H₂O

Na₂SO₃ + 2HCl  = 2NaCI + SO₂↑ + H₂O

SO₃²⁻ + 2H⁺=  SO₂↑ + H₂O

MgCI₂ + 2NaOH  = Mg(OH)↓ +2 NaCI

Mg²⁺ + 2CI⁻ + 2Na⁺ + 2OH⁻ = Mg(OH)↓ +2Na⁺ + 2CI⁻

Mg²⁺  2OH⁻ = Mg(OH)↓

KOH + HNO₃ = KNO₃ + H₂O

K⁺ + OH⁻ + H⁺ + NO₃⁻ = K⁺ + NO₃⁻ + H₂O

OH⁻ + H⁺ = H₂O

K₂CO₃ + H₂SO₄ = K₂SO₄ + CO₂↑ + H₂O

2K⁺ + CO₃²⁻ + 2H ⁺ + SO₄²⁻ = 2K⁺ + SO₄²⁻ + CO₂↑ + H₂O

CO₃²⁻ + 2H⁺  =  CO₂↑ + H₂O

CuSO₄ + 2KOH  = Cu(OH)₂↓ +  K₂SO₄

Cu²⁺ + SO₄²⁺ + 2K⁺ + 2OH⁻  = Cu(OH)₂↓ +  2K⁺ + SO₄²⁻

Cu²⁺ + SO₄²⁺ + 2K⁺ + 2OH⁻  = Cu(OH)₂↓

NaOH + HCl = NaCl  + H₂O

Na⁺ + OH⁻ + H⁺ + Cl⁻ = Na⁺ + Cl⁻  + H₂O

OH⁻ + H⁺ =  H₂O
