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 lattice energy of the solid versus the hydration energy of the ions.

Step 2: Recognize that ionic compounds containing alkali metal ions (like Na⁺) and nitrate ions (NO₃⁻) are generally very soluble in water due to strong ion-dipole interactions with water molecules.

Step 3: Compare the given compounds: AgCl, PbBr₂, BaSO₄ are all salts with ions that tend to form less soluble compounds because of higher lattice energies and lower hydration energies relative to NaNO₃.

Step 4: Recall the solubility rules: nitrates (NO₃⁻) are typically soluble with no common exceptions, while chlorides, bromides, and sulfates have varying solubilities and often form precipitates with certain cations.

Step 5: Conclude that NaNO₃ is the most soluble compound among the options because it fully dissociates in water and does not form a precipitate, unlike the other salts listed.
