C
BaSO_4
D
AgCl
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 nitrates (NO_3^-) are generally soluble in water regardless of the cation, so NaNO_3 is expected to be soluble.
Recognize that sulfates (SO_4^{2-}) have varying solubility: PbSO_4 and BaSO_4 are known to be poorly soluble or insoluble in water.
Understand that most chlorides (Cl^-) are soluble, but silver chloride (AgCl) is an exception and is poorly soluble in water.
Conclude that among the given salts, only NaNO_3 is soluble in water based on these solubility rules.
