What will come in place of A and B, respectively, in the given double displacement reaction?
A + B → AgBr + KNO₃

Correct option is D

The correct answer is (D) AgNO₃ and KBr.

• The given reaction is a double displacement reaction where the cations and anions of two compounds exchange places to form two new compounds. The reaction is as follows:

AgNO₃+KBr→AgBr+KNO₃

Explanation:

• Silver nitrate (AgNO₃) reacts with potassium bromide (KBr).
• The Ag⁺ ion from silver nitrate combines with the Br⁻ ion from potassium bromide to form silver bromide (AgBr), which is a precipitate.
• The K⁺ ion combines with the NO₃⁻ ion to form potassium nitrate (KNO₃), which remains in solution.
