Verified step by step guidance1
Identify the compounds given: CaCO3 (calcium carbonate), K2SO4 (potassium sulfate), N2O3 (dinitrogen trioxide), and BaSO4 (barium sulfate).
Recall the common solubility rules: most alkali metal salts (like potassium compounds) and nitrates are soluble in water; carbonates and sulfates have varying solubility depending on the cation.
Apply the solubility rules to each compound: calcium carbonate (CaCO3) is generally insoluble, potassium sulfate (K2SO4) is soluble because potassium salts are soluble, dinitrogen trioxide (N2O3) is a molecular compound and its solubility depends on different factors, and barium sulfate (BaSO4) is generally insoluble.
Compare the solubility tendencies and identify which compound is most likely to dissolve in water based on these rules.
Conclude that the compound containing potassium (K2SO4) is most likely soluble in water due to the high solubility of potassium salts.
