Answer. BaSO4 ,SrSO4,CaSO4 are all insoluble in water but to a different extent. Sulphates of Beryllium and Magnesium are soluble in water. But, Sulphates of Calcium, Strontium and Barium (CaStroBeAr) are not soluble to different extent.
Is barium sulfate BaSO4 soluble or insoluble in water?
Sulfuric acid
Barium sulfate/Soluble in
It is virtually insoluble in water (285 mg/l at 30 °C) and insoluble in alcohol. Its Ksp is 1.1 × 10–10. It is soluble in concentrated sulfuric acid. The crystal structure of BaSO4 is known to be rhombic, with a space group pnma.

Is BaSO4 soluble or not?
Barium sulfate is a metal sulfate with formula BaO4S. Virtually insoluble in water at room temperature, it is mostly used as a component in oil well drilling fluid it occurs naturally as the mineral barite.
Which is soluble in water BaSO4 CaSO4 SrSO4 BaSO4?
These hydration enthalpy values are higher than their corresponding lattice enthalpies and therefore BeSO4 and MgSO4 are highly soluble in water. However hydration enthalpies of CaSO4 SrSO4 and BaSO4 are not very high as compared to their respective lattice enthalpies and hence these are insoluble in water.
Why are BeSO4 and MgSO4 readily soluble in water while CaSO 4 SrSO4 and BaSO4 are insoluble?
While BeSO4 and MgSO4 are readily soluble in water, CaSO4, SrSO4, and BaSO4 are insoluble. This is because the greater hydration enthalpies of Be2+ and Mg2+ ions overcome the lattice enthalpy factor and therefore their sulphates are soluble in water.
Which is more soluble BaSO4 or BaSO4?
– Solubility of salt largely depends on its ionization, size of cation and charge on the ion. – Smaller cations are more soluble in water. – Between Be & Ba, Be ion has small ionic size. – Therefore, BeSO4 is more soluble than BaSO4.
Why barium sulphate is not soluble in water?
Whereas, barium sulphate is not at all soluble in water. It is one of the most insoluble ionic salts. This is because the sizes of barium ion and sulphate ion are almost similar and thus the compound has a very high lattice energy which is significantly greater than its hydration energy.
Why is SrSO4 insoluble in water?
SrSO4 known as Strontium sulfate is poorly soluble in water to about g/100ml at 25 °C: 0.0135 (very poor). The hydration enthalpy of Sr2+ cannot overcome their high lattice enthalpy and therefore most of the time remains insoluble in water.
Which ions are in SrSO4?
sulfate is formed from Strontium (Sr 2+ ) cation and Sulfate ( 2 4 SO − ) anions.
Is BaSO4 an electrolyte?
Barium sulfate is a strong electrolyte.
Why is MgSO4 soluble in water whereas BaSO4 is insoluble in water?
More the lattice energy, less the solubility. Thus compounds containing ions with a -2 charge are normally not soluble in water. BaSO4 has Ba2+ and So4 2-. MgSO4 is composed f relatively low charged ions and thus it is very soluble in water.
Where can I study solubility Order of beso4 for NEET?

What is the solubility of CaSO4 at 25 degrees Celsius?
The solubility of CaSO4 at 25 ºC is described by the following reaction and equilibrium CaSO4(s) ↔ Ca2+ + SO42- Ksp(CaSO4) = [Ca2+][SO42-] = 2.4∙10-5 eq. 1
What is the product of KSP(CaSO4) and SO42-?
Ksp(CaSO4) = [Ca2+][SO42-] = 2.4∙10-5 eq. 1 In words, this equilibrium expression implies that the product of the calcium ion concentration and the sulfate ion concentration can be no larger than 2.4∙10-5 in any aqueous solution.
