Verified step by step guidance

Step 1: Understand that solubility in water depends largely on the compound's ability to dissociate into ions and the solubility rules for ionic compounds. Water is a polar solvent, so ionic compounds that dissociate easily tend to be more soluble.

Step 2: Recall the common solubility rules: most nitrates (NO_3^-) are soluble in water, while many chlorides, sulfates, and carbonates have varying solubilities depending on the cation.

Step 3: Analyze each compound: AgCl is a chloride but silver chloride is known to be poorly soluble; BaSO_4 is a sulfate but barium sulfate is also poorly soluble; CaCO_3 is a carbonate and generally sparingly soluble in water.

Step 4: NaNO_3 contains the nitrate ion, which is almost always soluble in water regardless of the cation, and sodium ions are highly soluble as well.

Step 5: Conclude that based on solubility rules and the nature of the ions, NaNO_3 would be the most soluble compound in water among the options given.
