Why is BeF2 soluble in water?

BeF2 is soluble in water due to evolution of large hydration energy, when it is dissolved in water, which is sufficient enough to overcome the lattice energy of the Berylium Flouride, as for a compound to be soluble in water, the lattice energy of the compound must be less than the hydration energy evolved upon …

Why is LiF not soluble in water?

Due to the small size of Li+ ion and F- ions, the lattice energy of LiF is very high. LiF is covalent in nature. Therefore, LiF is insoluble in water.

Why is BeF2 most soluble?

->BeF2 : is soluble in water due to evolution of large hydration energy, when it is dissolved in water, which is sufficient enough to overcome the lattice energy of the Berylium Flouride, as for a compound to be soluble in water, the lattice energy of the compound must be less than the hydration energy evolved upon …

Would BeF2 dissolve in water?

Beryllium fluoride is the inorganic compound with the formula BeF2. This white solid is the principal precursor for the manufacture of beryllium metal. Its structure resembles that of quartz, but BeF2 is highly soluble in water.

Which is more soluble in water BeF2 or BaF2?

Here is the answer to your question: BaF2 being more ionic in nature, will be more solube in polar solvents like water.

Why BeF2 is more stable than BaF2?

BeF2 is more stable than BaF2 because fluoride ion is a small anion and small anion is stabilised by small cation . Be cation is smaller than Ba cation.

Why LiF is insoluble in water but LiCl is soluble?

Due to high lattice enthalpy of LiF as compared to LiCl, LiF is almost insoluble in water. LiCl is soluble in acetone also due to larger anion as compared to cation, polarization occur and thus LiCl posses some covalent character.

Which of following is highly soluble in water?

Owing to the high hydration energy of Be2+ (-2494kJmol-1) in forming [Be(H2O)4]2+ beryllium fluoride is very soluble in water.

Is BeF2 more soluble than BaF2?

Is BeF2 more soluble in water than BaF2?

Be cation is smaller than Ba cation. Sorry i interpreted the question wrong BaF2 is more soluble than BeF2 because for molecules having small anions like flouride , oxide ,hydroxides etc solubility increases down the group because lattice energy decreases .
