What is more soluble NaCl or KCl?
NaCl is more soluble in water than KCl. Solubility depends on the size of the cation as the anion is the same. The solubility of NaCl is 359 g/L at 200C and the solubility of KCl is 344 g/L at 200C.
Why LiCl is more soluble in water than NaCl?
For all having same charge of +1, the ionic size of lithium is smaller than sodium and potassium ions, making it having high charge density and high polarising power. Hence, water is polarised by lithium ion easier and LiCl is more soluble.
Which is more soluble LiCl or KCl?
Smaller the cation, greater is its polarizing power and hence larger is the covalent character. Thus LiCl is more covalent than KCl and hence KCl is more soluble in water because of decreased covalent character.
Which is more soluble KCl or LiCl?
The covalent character of any compound in general depends upon the size of the cations. 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 LiCl more soluble than KCl?
Although lithium fluoride and magnesium oxide contain cations and anions of roughly the same size, lithium fluoride is much more soluble in water (2.7 g/L) than magnesium oxide (0.087 g/L) at room temperature….Problem 3.4. 3.
| Compound | Water Solubility in g/L at 20oC |
|---|---|
| LiCl | 83 |
| NaCl | 359 |
| KCl | 344 |
Why is LiCl less soluble than NaCl?
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.
Why is LiCl less soluble in water?
A. For a substance to dissolve in water, its hydration energy must be greater than its lattice energy. Due to the larger size of \[C{I^ – }\] ion, the lattice energy of LiCl is less than its hydration energy.
Which one is more soluble in water KCl or NaCl?
Both of them are inorganic salt, and hence highly soluble in water. Nacl is more soluble in water than Kcl. Solubility also depends on the size of the cation as the anion is common in the case.
Why is K+ more polarizable than Na+ and KCl?
For NaCl, LiCl, KCl ; K+ is bigger in size and more polarizable than that of Na+ & Li+ . In periodic table , size of atom increases within down the group. So, K+>Na+>Li+ , size decreases steadily. Li+ is smaller in size and more polarizable than that of Na+, K+.
What is the melting point of LiCl and NaCl?
LiCl= 605°c, NaCl=800°C, KCl = 776°C, RbCl = 715°C, CsCl = 625°C). should increase as NaCl < KCl < RbCl < CsCl. The melting points however, decrease from LiCl= 605°c, NaCl=800°C, KCl = 776°C, RbCl = 715°C, CsCl = 625°C). should increase as NaCl < KCl < RbCl < CsCl.
Why is LiCl more covalent than Na+ and K+?
Li+ is smaller in size and more polarizable than that of Na+, K+. Li+ is distorted outmost electron cloud of Cl-. Since, covalency of compound is directly propotional to the polarising power of cation. So, LiCl is more covalent.
