Question

What happens when silver nitrate solution is added to sodium chloride solution ?
(a) Write the equation for the reaction which takes place.
(b) Name the type of reaction involved.​

Answer 1

Explanation:

Given -

• When silver nitrate is added to sodium chloride solution

To Find -

• Write the equation for the reaction which takes place
• Name the type of reaction involved

When silver nitrate is added to sodium chloride solution then it forms silver chloride and sodium nitrate

Chemical equation :-

AgNO3 + NaCl → AgCl2 + NaNO3

This is the example of Double displacement reaction.

Types of chemical reaction :-

• Combination reaction -

Those reaction in which two or more substances combined to form a single substance, are called combination reaction.

combination reaction.

Example -

C + O2 → CO2

• Decomposition reaction -

Those reaction in which a compound splits up into two or more simpler substances are known as decomposition reaction.

decomposition reaction.

Example -

CaCO3 → CaO + CO2

• Displacement reaction -

Those reaction in which one element takes the place of another element in a compound, are known as Displacement reaction.

Displacement reaction.

Example -

CuSO4 + Zn → ZnSO4 + Cu

• Double Displacement reaction -

Those reaction in which two compounds react by an exchange of ions to form two new compounds are called double displacement reaction.

Example -

AgNO3 + NaCl → AgCl + NaNO3
