Question

Consider the reaction:

\[\ce{KBr_{(aq)} + AgNO3_{(aq)} -> KNO3_{(aq)} + AgBr_{(s)}}\]

This is an example of:

पर्याय

• decomposition reaction

• combination reaction

• double displacement reaction

• displacement reaction

Answer 1

Double displacement reaction

Explanation:

In a double displacement reaction, potassium bromide (KBr) and silver nitrate (AgNO₃) exchange their constituent ions (K⁺, Ag⁺, Br⁻, and \[\ce{NO^-_3}\]) to form two entirely new compounds. Because an insoluble solid, silver bromide (AgBr), is produced, it is also specifically classified as a precipitation reaction.
