Figuring out an unknown solution?

[oliviarose]

So, basically I am extremely confused by some of my chemistry homework. The question is: "hypothetically, you have an unknown solution that contains either dissolved NaCl or dissolved NaNO_3. You add AgNO₃ to the unknown solution and observe that a precipitate forms. Identify the unknown solution and explain your choice (use the solubility rules)." I'm confused because wouldn't both NaCl + AgNO₃ and NaNO₃ + AgNO₃ create a precipitate? Couldn't the unknown solution technically be both options? I'm so confused.

What is solubility of AgCl (in water).. ?
