Consider the equation below.

[tex]\[ \text{AgNO}_3 (\text{aq}) + \text{NaCl} (\text{aq}) \rightarrow \text{AgCl} (\text{s}) + \text{NaNO}_3 (\text{aq}) \][/tex]

Which compound is the precipitate in this chemical reaction?

A. [tex]\(\text{AgNO}_3\)[/tex]
B. [tex]\(\text{NaCl}\)[/tex]
C. [tex]\(\text{AgCl}\)[/tex]
D. [tex]\(\text{NaNO}_3\)[/tex]



Answer :

To determine which compound is the precipitate in the given chemical reaction:

[tex]\[ AgNO_3(aq) + NaCl(aq) \rightarrow AgCl(s) + NaNO_3(aq) \][/tex]

we need to recognize the states provided. The states are denoted as follows:
- (aq) means aqueous, indicating that the compounds are dissolved in water.
- (s) means solid, indicating that the compound is a solid precipitate.

In the given equation, the products are AgCl and NaNO_3. Among these, the compound that is listed with the (s) indicates it is a solid precipitate.

From the equation:
- [tex]\(AgNO_3(aq)\)[/tex]: aqueous
- [tex]\(NaCl(aq)\)[/tex]: aqueous
- [tex]\(AgCl(s)\)[/tex]: solid (precipitate)
- [tex]\(NaNO_3(aq)\)[/tex]: aqueous

Thus, the compound which forms a precipitate (solid) in this reaction is [tex]\(AgCl\)[/tex].

Therefore, the precipitate in this chemical reaction is AgCl.

Additionally, from the list of given options:
- [tex]\( AgNO_3 \)[/tex]
- NaCl
- AgCl
- [tex]\( NaNO_3 \)[/tex]

AgCl is listed as the third option. Thus, AgCl is the correct answer located at index 2 in the list of options.
