1) AgCl is insoluble in water because Ag from group I cations which precipitated as chloride. (Ksp = 1.6 x 10⁻¹⁰)

2) CaCO₃ also insoluble in water because Ca from group V cations which precipitated as carbonate. (Ksp = 3.6 x 10⁻⁹)

3) Na₂CO₃ soluble in water because Na from group VI which called soluble group and all carbonates are insoluble in water except Na, K, and NH₄

4) SrSO₄ insoluble in water due to it is from group V which precipitated also as sulfate and has low (Ksp 2.8 x 10⁻⁷)

So the correct answer is Na₂CO₃

It is not all compounds that are soluble in water. According to table F which substance is most soluble in water is Na₂CO₃ .

  • Na₂CO₃ is known to be very soluble in water. This is because of the sodium. Sodium is found in group VI of the periodic table. The elements in that group are regarded as soluble group. All carbonates are known to be insoluble in water except the ones of Na, K, and NH₄.

It is often found naturally in arid regions where  mineral deposits (evaporites) are formed.

Water is known to be able to dissolve Sodium carbonate because there is a positive portion of water molecules that compels or attracts the negative carbonate ions and the negative portion of water molecules that attracts the positive sodium ions.
