'''염화 은'''({{llang|en|Silver chloride}})은 물에 잘 녹지 않는 [[염]]으로, 유명한 [[앙금 생성 반응]] 물질이다. 용해도곱상수는 K<sub>sp</sub> = 4.0{{e|-10}}이고 용해도는 0.52mg/물 100g(50&nbsp;°C일 때)이다.

은 이온과 염화 이온이 반응하여 흰색 앙금인 염화 은이 생성된다.

== 생성 반응 ==
생성 반응은 다음과 같다.
* XCl + AgNO<sub>3</sub> → XNO<sub>3</sub> + AgCl↓(X : [[알칼리 금속]])

== 구조 및 반응 ==
* AgCl(s) + Cl<sup>−</sup>(aq) → AgCl<sub>2</sub><sup>−</sup>(aq)
* AgCl(s) + 2S<sub>2</sub>O<sub>3</sub><sup>2−</sup>(aq) → [Ag(S<sub>2</sub>O<sub>3</sub>)<sub>2</sub>]<sup>3−</sup>(aq) + Cl<sup>−</sup>(aq)
* AgCl(s) + 2NH<sub>3</sub>(aq) → [Ag(NH<sub>3</sub>)<sub>2</sub>]<sup>+</sup>(aq) + Cl<sup>−</sup>(aq)

== 화학 ==
알짜이온 반응식은 다음과 같다.

* Ag<sup>+</sup>([[수용액|aq]]) + Cl<sup>−</sup>(aq) → AgCl([[고체|s]])

== 용도 ==
햇빛에 노출시키면 [[은]]이 유리되어 검게 변하므로, 감광지의 원료나 [[사진]] 등에 쓰인다.
