Verified step by step guidance

Recall the common solubility rules for ionic compounds in water: most nitrates (NO3-) are soluble, alkali metal salts (like Na+ and K+) are soluble, and most chlorides (Cl-) are soluble except those of Ag+, Pb2+, and Hg2+ which are often insoluble or partially soluble.

Analyze each compound based on these rules: AgNO3 contains nitrate, which is generally soluble; NaNO3 also contains nitrate and an alkali metal, so it is soluble; K2SO4 contains an alkali metal and sulfate, which is generally soluble.

Consider PbCl2: lead(II) chloride is an exception to the chloride solubility rule because Pb2+ forms a compound with chloride that is only partially soluble in water.

Therefore, among the given compounds, PbCl2 is the one that is considered partially soluble in water according to common solubility rules.

Summarize that understanding solubility rules helps predict whether a compound will dissolve fully, partially, or not at all in water, which is important for reactions and solution preparation.
