Which of the following compounds would you expect to be soluble in water?
A
AgCl
B
BaSO_4
C
PbSO_4
D
NaNO_3
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 barium sulfate (BaSO_4) and lead sulfate (PbSO_4) are also typically insoluble or only slightly soluble in water because most sulfates of heavy metals have low solubility.
Conclude that among the given compounds, NaNO_3 is the one expected to be soluble in water based on these solubility rules.
