Question

How would I know if Ag(aq) or S is used to make AgBr(s)?

A) Silver ions in an aqueous solution react with bromide ions.
B) Sulfur reacts with silver ions to form a precipitate of silver bromide.
C) Silver ions precipitate out with bromide ions forming a solid.
D) Sulfur ions react with bromine to form silver bromide.

Answer 1

Silver bromide (AgBr) is formed when silver ions (Ag+) in an aqueous solution react with bromide ions (Br-) to produce a pale yellow precipitate, not by the reaction involving sulfur or sulfur ions.

Step-by-step explanation:

In order to determine whether Ag+ (aq) or S is used to make AgBr (s), it is essential to understand the chemical reactions involved in forming silver bromide. The correct reaction for the formation of AgBr(s) is when silver ions in an aqueous solution react with bromide ions. The precipitation reaction is represented as:
Ag+(aq) + Br-(aq) → AgBr(s).

Neither sulfur nor sulfur ions are involved in the formation of silver bromide precipitate. Therefore, the correct statement that describes the formation of AgBr(s) is: A) Silver ions in an aqueous solution react with bromide ions. This reaction results in the precipitation of silver bromide, which appears as a pale yellow solid.
