Why is LiI less soluble in water?
– Lattice energy mainly depends upon two factor-charge and size. – As size decreases and charge increases, the lattice energy also increases and vice-versa. 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.
Which is more soluble in water sodium iodide or lithium iodide?
Hence, we expect that LiF is more soluble in water and LiI is less soluble or not soluble in water. The solubility of an ionic compound in water depends on the relative values of lattice energy and hydration energy. The substance becomes soluble in water if hydration energy exceeds lattice energy.
Why NaF is more soluble than LiF?
NaF is more soluble than LiF because of the larger size of NaF. LiF is formed by a lithium cation and a fluoride anion, and NaF is formed by a sodium cation and a fluoride anion. Therefore, NaF is more soluble in water than LiF.
Which is more soluble NaI or NaF?
5. The solubility trend of the sodium halide salts (NaF, NaCl, NaBr, NaI) is that the solubility increases with increasing ionic radius of the halide. In other words, NaI is more soluble than NaBr. NaBr is more soluble than NaCl and NaCl is more soluble than NaF.

Sodium iodide/Soluble in
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na+) and iodide anions (I−) in a crystal lattice.
Why is LiI more soluble than LiF?
LiF is more soluble in water. According to Fajans’s rule, FΘ ion, being smaller as compared as compared to IΘ ion, will be polarised to a greater extent. Hence LiF will be less convalent as compared to LiI and hence LiF will be more soluble in water as compared to LiI.
Is LiI more soluble than LiCl?
Stronger lattice energy results in less soluble crystal lattice. In each pair, determine which compound will have a higher lattice energy….3.4: Solubility.

Which is least soluble in water NaF LiF KF RbF?
LiF is least soluble among the fluorides of alkali metals.
Why is NaI very soluble in water?
NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).
