Based on general solubility rules, which of the following compounds is most likely to have the highest solubility in water?
A
AgCl
B
CaCO_3
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 is soluble or insoluble.
Identify that compounds containing alkali metal ions (like Na\+) and nitrate ions (NO_3^-) are generally soluble in water without exceptions.
Examine the given compounds: AgCl, CaCO_3, and PbSO_4 are all salts known to have low solubility or are sparingly soluble in water based on solubility rules.
Recognize that NaNO_3 contains the nitrate ion, which is highly soluble, making NaNO_3 much more soluble than the other listed compounds.
Conclude that among the options, NaNO_3 is most likely to have the highest solubility in water due to the presence of the nitrate ion and sodium ion, both of which promote solubility.
