Question

Silver chloride on exposure to sunlight decomposes into silver and chlorine gas. This property is used in
A. Heat production as enormous energy is released.

B. Silver extraction as earth contains silver mainly in silver chloride form.

C. Black and white Photography as formed grey silver form an image imprint.

D. None​

Answer 1

Answer

C. Black and white Photography as formed grey silver form an image imprint.

$\rule{200}2$

Explanation

Silver chloride on exposure to sunlight decomposes into silver and chlorine gas.

The following reaction will takes place-

$\sf{2AgCl \xrightarrow{Sunlight}2Ag+Cl_2}$

Silver chloride is white in colour but after decomposition silver becomes grey in colour. This reaction is used in black and white photography.

The above reaction is an example of Decomposing Reaction.

What is Decomposition Reaction?

Reaction in which a single reactant break down into two or more products. Such type of reaction is known as Decomposition reaction.

There are three types of Decomposition Reaction:

1. Thermal decomposition reaction
2. Photo decomposition reaction
3. Electric decomposition reaction

Answer 2

Answer:

c)Black and white photography as formed grey silver form an image imprint.....

Explanation:

When silver chloride is exposed to light, it decomposes to form silver metal and chlorine gas.

2AgCl(s)-------->2Ag(s)+Cl2(g)

This reaction is used in black and white photography.

✍️These reaction is decomposition reaction.

✏️DECOMPOSITION REACTION ✏️

A decomposition reaction can be defined as a type of chemical reaction in which under suitable conditions, one single compound splits into multiple simpler substances.

Types of decomposition reaction:

⚕️ Thermal decomposition reaction

⚕️ Electrolytic decomposition reaction

⚕️ Photochemical decomposition reaction
