Verified step by step guidance

Step 1: Understand that solubility in water depends on the compound's ability to dissociate into ions and the lattice energy of the solid versus the hydration energy of the ions formed.

Step 2: Recognize that ionic compounds with highly soluble ions (like Na+ and NO3-) tend to be more soluble in water because the hydration energy overcomes the lattice energy.

Step 3: Recall common solubility rules: nitrates (NO3-) are generally soluble in water, while carbonates (CO3^2-), sulfates (SO4^2-), and chlorides (Cl-) have varying solubilities depending on the cation.

Step 4: Compare the given compounds: CaCO3, BaSO4, and AgCl are known to be sparingly soluble or insoluble in water, while NaNO3 is highly soluble due to the nitrate ion.

Step 5: Conclude that NaNO3 is expected to be the most soluble in water because it contains the nitrate ion, which forms compounds that are generally very soluble.
