Answer 2

Solubility of Substances in Water

The solubility of substances in water can vary depending on their chemical properties. In the given options, the solubility of the substances can be determined by considering their chemical formulas and the solubility rules.

Option A: Ba(NO3)2, BaCl2, BaCO3 - Ba(NO3)2 (barium nitrate) is soluble in water. [[1]] - BaCl2 (barium chloride) is soluble in water. [[1]] - BaCO3 (barium carbonate) is insoluble in water. [[1]]

Option B: Ag3PO4, AgCI, AgNO3 - Ag3PO4 (silver phosphate) is insoluble in water. [[1]] - AgCI (silver chloride) is insoluble in water. [[1]] - AgNO3 (silver nitrate) is soluble in water. [[1]]

Option C: K2SO4, BaSO4, ZnSO4 - K2SO4 (potassium sulfate) is soluble in water. [[1]] - BaSO4 (barium sulfate) is insoluble in water. [[1]] - ZnSO4 (zinc sulfate) is soluble in water. [[1]]

Option D: K2SO3, Li2SO4, Na3PO4 - K2SO3 (potassium sulfite) is soluble in water. [[1]] - Li2SO4 (lithium sulfate) is soluble in water. [[1]] - Na3PO4 (sodium phosphate) is soluble in water. [[1]]

Based on the solubility rules, the correct answer is Option A: Ba(NO3)2, BaCl2, BaCO3. Ba(NO3)2 and BaCl2 are soluble in water, while BaCO3 is insoluble in water.
