PbSO_4

Verified step by step guidance

Recall the general solubility rules for ionic compounds in water: most nitrates (NO_3^-) are soluble, most carbonates (CO_3^{2-}) and sulfates (SO_4^{2-}) have limited solubility, and most chlorides (Cl^-) are soluble except those of silver (Ag^+), lead (Pb^{2+}), and mercury (Hg_2^{2+}).

Analyze each compound based on these rules: NaNO_3 contains the nitrate ion, which is generally soluble; CaCO_3 contains carbonate, which is mostly insoluble except with alkali metals; AgCl contains chloride but silver chloride is known to be poorly soluble; PbSO_4 contains sulfate, but lead sulfate has low solubility.

Compare the solubility tendencies: NaNO_3 is expected to be highly soluble due to the nitrate ion, while CaCO_3, AgCl, and PbSO_4 are all sparingly soluble or insoluble in water.

Conclude that among the given options, NaNO_3 is the most soluble compound in water based on the solubility rules.

Remember that these rules are empirical guidelines and exceptions exist, but for this problem, applying the general solubility rules is sufficient to determine the most soluble compound.
