当锌粒与稀释的H₂SO₄、HCl、HNO₃、NaCl和NaOH溶液反应时会发生什么？<b>如果发生反应，请写出化学方程式。</b>

学术化学 NCERT 10年级

当锌粒与稀释的H₂SO₄反应时，会发生置换反应，生成ZnSO₄并释放H₂气体。

$Zn( s)+ H_2SO_4(aq)→ ZnSO_4 (aq)+H_2 (g)$

当锌粒与稀释的HCl反应时，会发生置换反应，生成ZnCl₂并释放H₂气体。

$Zn( s)+ HCl(aq) →ZnCl_2 (aq)+H_2 (g)$

当锌粒与稀释的HNO₃反应时，会生成硝酸锌，并释放H₂O和一氧化二氮。

$4Zn(s)+10 HNO_3(aq)→ 4Zn(NO_3)_2(aq) +5H_2O(i)+N_2O (g)$

当锌粒与NaCl反应时，不会发生反应。

当锌粒与NaOH溶液反应时

$Zn(s)+ NaOH(aq)→ Na_2ZnO_2 (aq)+H_2 (g)$
