NaNO_3
D
BaSO_4
Verified step by step guidance1
Recall the general solubility rules for ionic compounds in water, which help predict whether a compound will dissolve.
Note that most nitrates (NO_3^-) are soluble in water without exception, so NaNO_3 is expected to be soluble.
Recognize that silver chloride (AgCl) is generally insoluble in water due to the low solubility of most silver halides.
Understand that lead sulfate (PbSO_4) and barium sulfate (BaSO_4) are both sulfates, but sulfates of lead and barium are typically insoluble or only slightly soluble in water.
Conclude that among the given compounds, NaNO_3 is soluble in water based on the solubility rules, while AgCl, PbSO_4, and BaSO_4 are not.
