Final answer:
The correct statement about the reaction NaCl(aq) + AgNO3(aq) ® AgCl(s) + NaNO3(aq) is that AgCl is a solid in this reaction, indicating that it forms a precipitate and is not soluble in water.
Step-by-step explanation:
Considering the equation NaCl(aq) + AgNO3(aq) ® AgCl(s) + NaNO3(aq), the correct statement among the options given is that AgCl is a solid in this reaction. This is a representation of a double-replacement reaction, also known as a metathesis reaction, where the anions and cations of two different molecules switch places, forming two entirely different compounds.
The precipitate in this reaction is silver chloride (AgCl), indicated by the (s) after its formula, which stands for solid, meaning it is not soluble in water. Therefore, option b stating that AgCl is soluble is incorrect. The substances with (aq) after their formulas, such as NaCl, AgNO3, and NaNO3, are soluble in water and are present as aquatic solutions, indicating they exist as ions in water. Thus, options a and c, which suggest NaCl and NaNO3 are solids in the reaction, are not true, and option d is also false as AgNO3 is not a gas.
