Why is soluble but BaSO4 is insoluble in water?
Barium sulphate is insoluble in water because it has a high lattice energy. On adding water in barium sulphate its hydration energy decreases more rapidly in comparison to its lattice energy. The solvation energy tends to increase the solubility of ionic substances.
Which is more soluble in water BaSO4 or BaSO4?
– Smaller cations are more soluble in water. – Between Be & Ba, Be ion has small ionic size. – Therefore, BeSO4 is more soluble than BaSO4.
Why BaSO4 is insoluble in water whereas MgSO4 is soluble?
Hence, due to decreasing hydration energy , the solubility of sulphates decreases down the group, and as Mg is very smaller than Ba, in size so the MgSO4 but at the bottom of the group the solubility of BaSO4 becomes least and it becomes insoluble in water.
How would you explain the following observations I BaO is soluble but BaSO4 is insoluble in water?
(ii) Lattice energy of BaO is much smaller than that of its hydration energy, so it is soluble in water . in BaSO4 , Lattice energy predominates over hydration energy so, it is insoluble in water.
Why BaO is soluble in water?
The lattice enthalpy of BaO is less than its hydration enthalpy, because of the large size of Ba ions and smaller size of the oxide ion. Therefore BaO is soluble in water.
Is BaSO4 least soluble in water?
BaSO4 is insoluble in water.
Why BaSO4 more covalent than MgSO4?
Answer: This is because :(A) Lattice energy of BaSO4 is greater than MgSO4(B)BaSO, is more covalent than MgSO4(C) Hydration energy of Mg2+ is greater than Ba2+(D) Lattice energy of MgSO4 is greater than BaSO. Reason :Lil has more lattice energy and more hydration energy in comparison is LiBr.
Is BaSO4 soluble or insoluble?
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 Bao soluble or insoluble in water?
Therefore BaO is soluble in water. On the other hand in BaSO4 the size of Ba ions and sulphate. ions are very large and therefore the lattice enthalpy is much larger than the hydration enthalpy. Therefore BaSO4 is insoluble in water.
Why is BaSO4 insoluble in water but not Ba2+ and SO42-?
On the other hand Ba2+ and SO42- both are large cation and anion respectively making the lattice energy released during formation large enough to be not easily overtaken by hydration energy of the ions. This makes BaSO4 insoluble in water.
What is the difference between BEO and Bao and beso4?
(i) BeO is almost insoluble but BeSO4 is soluble in water, (ii) BaO is soluble but BaSO4 is insoluble in water, (iii) LiI is more soluble than KI in ethanol. (i) is small in size so it has high polarising power and is also small in size.
What is the difference between barium sulfate and BaSO4?
Barium Sulfate is composed of a barium cation and the sulfate anion. The sulphur is attached to four oxygen atoms. BaSO 4 is a sulfate salt of barium and is found as mineral barite. It is a crystalline solid white which is insoluble in water and alcohol but soluble in concentrated acids.
