General description

Silver(I) chloride is a off-white solid which is slightly soluble in water. Silver(I) chloride turns black in the presence of heat, indicating the formation of silver.
It can be produced easily through the combination of silver nitrate, sodium chloride, or cobalt(II) chloride.

Application

Silver chloride (AgCl) is widely employed as a catalyst, antibacterial agent, photographic material, and ionic semiconductor material.
Silver chloride (AgCl) can be used for a variety of applications such as: the coating on the silver wire that can be used as a reference electrode in electrochemistry
It can be deposited on conducting material for stable photocatalysis under visible light .
In addition, Silver(I)chloride is used to synthesis polymeric silver(I) complexes with 1D and 3D network .
Moreover, Silver(I)chloride is also used as a catalyst in the preparation of 1,2,3-triazoles from alkynes and azides.
