Fe²⁺ + 2OH⁻ = Fe(OH)₂↓
FeCI₂ + 2NaOH = Fe(OH)₂↓ + 2NaCI
Fe²⁺ + 2CI⁻ + 2Na⁺ + 2OH⁻ = Fe(OH)₂↓ + 2Na⁺ + 2CI⁻
Fe²⁺ + 2OH⁻ = Fe(OH)₂↓
FeCI₂ + 2NaOH = Fe(OH)₂↓ + 2NaCI
Fe²⁺ + 2CI⁻ + 2Na⁺ + 2OH⁻ = Fe(OH)₂↓ + 2Na⁺ + 2CI⁻
Fe(2+) + 2NO3(-) + 2Na(+) + 2OH(-) = Fe(OH)2 + 2Na(+) + 2NO3(-)
Fe(2+) + 2OH(-) = Fe(OH)2.
