Silver halides to be kept in colored bottles

Explanation:

Yes , this is true that silver halides are kept in dark or colored bottles because when they are exposed to sunlight , it undergoes photo decomposition .

Decomposition reaction

The reaction in which the compound splits into is constituents either by :

• By Heating : Thermal decomposition : Example : HgO--> Hg +O₂
• In presence of light  : Photo decomposition : Example : AgCl--> Ag + Cl₂
• By passing electricity : Electrolytic decomposition:Example: NaCl--> Na + Cl₂

So, in the above asked question it is correct .
