Understand the concept of solubility: Solubility refers to how well a substance dissolves in a solvent, such as water. Compounds with low solubility do not dissolve well in water and often form precipitates.
Recall common solubility rules for ionic compounds in water: Most alkali metal salts (like K_2SO_4 and NaNO_3) and ammonium salts (like NH_4Cl) are generally soluble in water.
Identify the compound that is known to have low solubility: Silver chloride (AgCl) is a classic example of a compound with low solubility in water, often used to demonstrate precipitation reactions.
Compare the given options against these rules: K_2SO_4, NH_4Cl, and NaNO_3 are all soluble, while AgCl is sparingly soluble and tends to precipitate out of solution.
Conclude that AgCl is the compound with low solubility in water based on solubility rules and common chemical knowledge.
