Mg + Br₂ = MgBr₂
MgBr₂ + 2KOH = Mg(OH)₂↓ + 2KBr
Mg²⁺ + 2Br⁻ + 2K⁺ + 2OH⁻ = Mg(OH)₂↓ + 2K⁺ + 2Br⁻
Mg²⁺ + 2OH⁻ = Mg(OH)₂↓
Mg(OH)₂ + 2HCl = MgCl₂ + 2H₂O
Mg(OH)₂ + 2H⁺ + 2Cl⁻ = Mg²⁺ + 2Cl⁻ + 2H₂O
Mg(OH)₂ + 2H⁺ = Mg²⁺ + 2H₂O
MgCl₂ + 2AgNO₃ = Mg(NO₃)₂ + 2AgCl↓
Mg²⁺ + 2Cl⁻ + 2Ag⁺ + 2NO₃⁻ = Mg²⁺ + 2NO₃⁻ + 2AgCl↓
2Ag⁺ + 2Cl⁻ = 2AgCl↓
