According to solubility rules, if a substance is soluble in water, then it is likely:

Recognize that ionic compounds containing alkali metal ions (like Na\textsuperscript{+}, K\textsuperscript{+}) or nitrate ions (NO\textsubscript{3}\textsuperscript{-}) are generally soluble because these ions interact favorably with water molecules.

Contrast this with nonpolar covalent compounds, which do not dissolve well in water due to lack of polarity, and insoluble salts like AgCl, which do not dissociate significantly in water.
