Verified step by step guidance

Step 1: Understand the concept of solubility, which is the ability of a substance to dissolve in a solvent, such as water. Solubility depends on the nature of the solute and solvent, and the interactions between their particles.

Step 2: Recognize that ionic compounds like NaNO_3, NH_4Cl, and K_2SO_4 are generally soluble in water because water is a polar solvent and can stabilize the ions formed when these compounds dissociate.

Step 3: Recall the solubility rules for common ionic compounds: nitrates (NO_3^-), ammonium salts (NH_4^+), and most sulfates (SO_4^{2-}) are typically soluble in water.

Step 4: Identify that silver chloride (AgCl) is an exception to these rules because it is known to be poorly soluble in water due to the strong ionic lattice and low hydration energy compared to the lattice energy.

Step 5: Conclude that among the given substances, AgCl is the least soluble in water because it does not dissociate significantly, unlike the other compounds listed.
