Question

When copper is dipped in the solution of silver nitrate, the solution turns blue. Give the reason along with the chemical equation?

Answer 1

A single-displacement reaction, is a chemical reaction in which one element is replaced by another in a compound. It can be represented generically as: $A+BC\to AC+B$. This will most often occur if A is more reactive than B, thus giving a more stable product.

Complete step by step solution:
We have been provided with copper metal,
Copper is a chemical element with the symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
Copper has been dipped in the solution of silver nitrate,
Silver nitrate is an inorganic compound with chemical formula $AgN{{O}_ {3}}$. This salt is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides.
When copper is dipped in the solution of silver nitrate,
$Cu+2AgN{{O}_ {3}} \to Cu{{(N{{O}_ {3}})} _ {2}} +2Ag$
Copper nitrate is formed along with silver metal,
Due to the formation of copper nitrate, the solution becomes blue in colour,
As copper nitrate is blue in colour.

Therefore, we can conclude that when copper is dipped in the solution of silver nitrate, the solution will become blue.

Note: The chemical reactivity of a substance can refer to the variety of circumstances (conditions that include temperature, pressure, presence of catalysts) in which it reacts, in combination with the: Variety of substances with which it reacts. Equilibrium point of the reaction (i.e., the extent to which all of it reacts).
