Question

salt that undergoes photochemical decomposition in copper sulphate with zinc carbonate lead Bromide and silver nitrate it is a correct answer​

Answer 1

Salt that undergoes photo chemical decomposition is silver nitrate AgNO₃​.

- Many salts of silver can undergo photo chemical decomposition.

-When silver nitrate is exposed to light it will decompose into its elements, i.e., then it produces silver (Ag), Nitrogen Dioxide (NO₂) and oxygen (O₂).

- This  photo chemical decomposition reaction can be represented as:

2AgNO₃ + sunlight ------> 2Ag + 2NO₂ + O₂

Answer 2

Silver nitrate (AgNO3) undergoes photo-chemical decomposition.

Option (c) is correct.

Explanation:

• When Silver Nitrate (AgNO3) is treated with photon light then it decomposes into respective ions or compounds.
• This reaction is known as photo-chemical decomposition reaction as the chemical composition of the salt undergoes changes.
• When light falls on silver nitrate salt then the salt gets separated into its component elements.
• The photo-chemical reaction is given below.
• 2 AgNO3 + (Sunlight)  ----> 2 Ag + 2NO2 + O2
• In this reaction it splits to form 2 molecules of nitrogen dioxide along with 2 silver atoms and oxygen molecule.
