Verified answer
ZnCl₂ + 2NaOh = Zn(OH)₂ + 2NaClZn²⁺ + 2Cl⁻ + 2Na⁺ + 2Oh⁻ = Zn(OH)₂ + 2Na⁺ + 2Cl⁻
Zn²⁺ + 2Oh⁻ = Zn(OH)₂
/
Zn(OH)₂ + 2HNO₃ = Zn(NO₃)₂+ 2H₂O
Zn(OH)₂ + 2H⁺ + 2NO₃⁻ = Zn²⁺ + 2NO₃⁻ + 2H₂O
Zn(OH)₂ + 2H⁺ = Zn²⁺ + 2H₂O
\
Zn(OH)₂ + 2NaOH = Na₂[Zn(OH)₄]
Zn(OH)₂ + 2Na⁺ + 2OH⁻ = 2Na⁺ + [Zn(OH)₄]²⁻
Zn(OH)₂ + 2OH⁻ = [Zn(OH)₄]²⁻
