Identify the solubility rules for common ionic compounds in water. Generally, nitrates (NO₃⁻) are soluble, while sulfates (SO₄²⁻), chlorides (Cl⁻), and carbonates (CO₃²⁻) have exceptions.
Examine the given compounds: NaNO₃, PbSO₄, AgCl, and CaCO₃.
Apply the solubility rule for nitrates: Compounds containing the nitrate ion (NO₃⁻) are soluble in water without exceptions.
Apply the solubility rule for sulfates: Most sulfates are soluble, but PbSO₄ is an exception and is insoluble.
Apply the solubility rule for chlorides and carbonates: AgCl is insoluble due to the presence of silver, and CaCO₃ is generally insoluble as most carbonates are.
