Verified step by step guidance1
Recall the general solubility rules for ionic compounds in water, which help predict whether a compound will dissolve (be soluble) or not (be insoluble).
Identify the common solubility trends: compounds containing alkali metal ions (like Na\^+) and nitrate ions (NO\_3\^-) are generally soluble in water.
Examine each compound: PbI\_2 (lead iodide) and AgCl (silver chloride) are typically insoluble or sparingly soluble due to the presence of heavy metal cations and halide ions.
BaSO\_4 (barium sulfate) is also known to be insoluble or only slightly soluble because sulfates of heavy alkaline earth metals tend to have low solubility.
NaNO\_3 (sodium nitrate) contains the sodium ion (Na\^+) and nitrate ion (NO\_3\^-), both of which are known to form soluble compounds, making NaNO\_3 the most likely to dissolve in water.
