'''氯化錫(II)'''，化學式[[錫|Sn]][[氯|Cl]]{{sub|2}}，為白色[[固體]]。

== 製備 ==
將[[錫]]溶於濃[[鹽酸]]中，再將溶液蒸發，製得無色針狀結晶SnCl{{sub|2}}‧2H{{sub|2}}O。反應式：

:<math>\ Sn+2HCl\to SnCl_2+H_2\uparrow</math>

== 性質 ==
溶於水中則水解生成[[鹼式]]氯化亞錫[Sn(OH)Cl]的白色沉澱。反應式：

:<math>\ SnCl_2+H_2O\to Sn(OH)Cl+HCl</math>

但可完全溶解於酸性溶液之中，並能成功進行[[置換反應]]。

:<math>\ SnCl_2 (aq) + Zn\to Sn + ZnCl_2 (aq) </math>

在酸性環境下易[[氧化]]成[[氯化錫]](IV)，為強[[還原劑]]。主要用作化学试剂、有机锡合成原料、电镀塑料电镀的敏化剂、香料的稳定剂、食品添加剂印染助剂、农药中间体、有机合成催化剂等,包含檢驗王水中是否含黃金(通常用於冶煉工藝)之確認使用
