Why is lithium chloride more soluble in water?
Polarizing power for cations is very much a case of increasing with increased ion charge/ionic radius. The covalent character decreases as size of cation increases LiCl > NaCl > KCl > RbCl > CsCl. Thus LiCl is more covalent than KCl and hence KCl is more soluble in water because of decreased covalent character.
Is potassium chloride or lithium chloride more soluble in water?
Lithium chloride is certainly the least water-soluble of the three compounds. That makes sense, since the lithium ions are small and the attraction for the chloride would be stronger over that shorter distance….Problem 3.4. 3.
| Compound | Water Solubility in g/L at 20oC |
|---|---|
| LiCl | 83 |
| NaCl | 359 |
| KCl | 344 |
Is Lithium chloride more soluble in water?
Lithium chloride is certainly the least water-soluble of the three compounds….3.4: Solubility.
| Compound | Water Solubility in g/100 mL at 20oC |
|---|---|
| LiCl | 83 |
| LiBr | 166 |
| LiI | 150 |
Why is lithium chloride less 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 lithium salts are less soluble in water?
That happens because of lithium’s small ionic size. SImply put, lithium carbonate is less soluble because the electrostatic attraction between the very small lithium cation and the carbonate anion overpowers the attraction between these ions and the water molecules.
Why are lithium salts less soluble in water?
Is lithium more soluble than potassium?
As a result of its small size, the lithium ion has a higher polarizing power than the potassium ion. It polarizes the electron cloud of the iodide ion to a much greater extent than the potassium ion. This causes a greater covalent character in LiI than in KI. Hence, LiI is more soluble in ethanol.
Why is lithium iodide more soluble than lithium chloride?
Since lattice energy of LiF is much greater than hydration energy, it is insoluble in water and thus solubility in water increases from LiF to LiI.
Why is lithium insoluble in water?
In Lithium fluoride the lattice enthalpy is very high due to small size of fluoride ions. In Lithium fluoride the lattice enthalpy is very high due to small size of fluoride ions. In this case the hydration enthalpy is very less. Hence, LiF is insoluble in water.
Why lithium fluoride almost insoluble in water whereas lithium chloride is soluble not only in water but also in acetone?
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.
Why lithium iodide is soluble in water?
Hydration energy – that energy released by the hydration of one mole of substance. But in LiI the lattice energy is having a small value and as lattice energy is having low value, the hydration enthalpy will be more, hence it is soluble in water.
