Question

13 multiple - choice question
which type of atoms did the silver re - couple with?
silver
nitrate
bromine
potassium

Explanation:

Step1: Analyze the reaction

In the reaction \(AgNO_3(aq)+KBr(aq)\to AgBr(s)+KNO_3(aq)\), we look at the ions involved. \(AgNO_3\) dissociates into \(Ag^+\) and \(NO_3^-\) ions, and \(KBr\) dissociates into \(K^+\) and \(Br^-\) ions.

Step2: Determine the coupling

\(Ag^+\) (from \(AgNO_3\)) couples with \(Br^-\) (from \(KBr\)) to form \(AgBr\) precipitate.

Answer:

bromine
