D
CaCO_3
Verified step by step guidance1
Recall the general solubility rules for ionic compounds in water, which help predict whether a salt will dissolve.
Note that salts containing alkali metal ions (such as Na\+) and nitrate ions (NO_3\-) are generally soluble in water.
Recognize that BaSO_4 (barium sulfate), AgCl (silver chloride), and CaCO_3 (calcium carbonate) are typically insoluble or sparingly soluble in water due to their specific ion interactions and lattice energies.
Apply the solubility rules to each salt: NaNO_3 is soluble because it contains Na\+ and NO_3\-, BaSO_4 is insoluble, AgCl is insoluble, and CaCO_3 is insoluble or sparingly soluble.
Conclude that among the given options, NaNO_3 is expected to be soluble in aqueous solution.
