2Na+(aq) + 2OH-(aq) + Zn2+(aq) + 2NO3-(aq) = Zn(OH)2(s) + 2Na+(aq) + 2NO3-(aq) Spectator Ions Spectator ions are ions that do not take part in the reaction. They are removed from the complete ionic equation to get the net ionic equation. Na+ NO3- ...
2NaOH(aq) + Zn(NO3)2(aq) = Zn(OH)2(s) + 2NaNO3(aq) might be an ionic reaction. Calculate the net ionic equation for 2NaOH(aq) + Zn(NO3)2(aq) = Zn(OH)2(s) + 2NaNO3(aq). Reactants Sodium Hydroxide - NaOH White Caustic Naoh Sodium Hydrate Soda Lye Lye Cau...

Zn2+ +4OH-＝Zn（OH）42- Zn2+ +4OH-＝ZnO2 2-+2H2O
Zn(NO3)2 + 2NaOH === Zn(OH)2↓ + 2NaNO3复分解反应发生的要求是要生成沉淀或者难电离的物质(初中要求是生成水、气体、沉淀).因为Zn(NO3)2与NaOH交换成分后有沉淀Zn(OH)2产生,所以反应向右进行. 解析看不懂?免费查看同类题视频解析查看解答 更多答案(2)...
