The hydration enthalpies of BeSO4 and MgSO4 are quite high because of small size of Be2+ and Mg2+ ions. These hydration enthalpy values are higher than their corresponding lattice enthalpies and therefore BeSO4 and MgSO4 are highly soluble in water.
Why BaSO4 is insoluble in water?
BaSO4 is insoluble in water because of water’s dipole strength. Since barium sulphate has strong crystals , water’s dipole strength is too weak to pull away the ions (anions and cations) from it, but very little amounts do dissociate.
What is the solubility product of BaSO4?
The solubility product (Ksp) of BaSO4 is 1.5 × 10^-9 .
Is barium sulfide soluble?
BaS is soluble in water (decomposes) but is insoluble in alcohol. Barium sulfide is prepared commercially by heating barite (BaO) with coal or petroleum coke in a rotary kiln at 1000 °C to 1250 °C in an oxygen-free atmosphere.
Why BaSO4 is less soluble than CaSO4?
The hydration enthalpies of BeSO4 and MgSO4 are quite high because of small size of Be2+ and Mg2+ ions. 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 is BaSO4 and MgSO4 soluble in water?
BaSO4 has Ba2+ and So4 2-. If the salt is composed of highly charged ions, it is insoluble in water. Anhydrous form of MgSO4 is hygroscopic and thus highly soluble in water. MgSO4 is composed f relatively low charged ions and thus it is very soluble in water.
Is BaSO4 insoluble or soluble?
Sulfuric acid
Barium sulfate/Soluble in
What is the solubility of BaSO4 in water in moles per Litre?
The solubility of BaSO4 in water is 2.42 x 10-3 gL-1 at 298 K. The value of its solubility product (Ksp) will be. (Given molar mass of BaSO4 = 233 g mo1-1) 1.08 x 10-14 mol2 L.

Is BaSO4 soluble or insoluble in water?
Barium sulphate, or BaSO4, is insoluble in water. It is a white crystalline solid. Barium sulphate is an odorless organic compound that is insoluble in most acids and bases and only soluble in hot, concentrated sulfuric acid.
What is the formula for BaSO4?
The formula of the chemical compound Barium sulfate is BaSO4
Why is BaSO4 insoluble in water?
BaSO4 is insoluble in water because of water’s dipole strength. Since barium sulphate has strong crystals , water’s dipole strength is too weak to pull away the ions (anions and cations) from it BaSO4 is insoluble in water because of water’s dipole strength is too weak as compare to baso4.
What is the Ksp for BaSO4?
BaSO4(s) <=> Ba+2(aq) + SO4–2(aq)) 1.00 liter of saturated BaSO4 solution will contain only ~0.0025 gram of dissolved BaSO4. The Equilibrium constant expression for this reaction can be written as: Ksp = [BaBa+2][SO4–2] Recall pure solids (and pure liquids) are not included in an equilibrium constant expression.
