Sodium chloride

Solid sodium chloride does not conduct electricity, because there are no electrons which are free to move. When it melts, sodium chloride undergoes electrolysis, which involves conduction of electricity because of the movement and discharge of the ions. In the process, sodium and chlorine are produced.

In an ionic compound, such as solid sodium chloride the free electrons are not present. Electrons are bound in bonds by strong electrostatic forces. So, sodium chloride does not conduct electricity in a solid-state. So, the reason for the conductivity of sodium chloride in the molten state is the presence of free ions.

So a molten salt powers electricity. Hence, molten sodium chloride conducts electricity due to the presence of free ions. So, the correct answer is option D. Note- The flow of electricity in chemical compounds can be due to free electrons as well as free ions.

KCl is more ionic because the ionic character increases as down the group while decreases along the period in the periodic table. Also, the bonding in KCl is more ionic than in NaCl. Electronegativity scales also support that NaCl is less ionic when compared to KCl.

From Wikipedia, the free encyclopedia. In inorganic chemistry, Fajans’ rules, formulated by Kazimierz Fajans in 1923, are used to predict whether a chemical bond will be covalent or ionic, and depend on the charge on the cation and the relative sizes of the cation and anion.

The covalent character is determined using Fajan’s rule. In the given compounds, the anion is the same and the cations are different. Therefore, MgCl2 is more covalent than NaCl. …

Because between LiCl & KCl cation size is decreasing in order Li is smaller than K and we know with decrease of size of cation increase the polarising power of cation. So polarishing power of Li is greater than K. So LiCl is more covalent than KCl.

In LiCl and KCl the anions are the same. From the periodic table, we can see that Li+ is smaller than K+.So in LiCl more polarisation occurs and makes it more covalent than KCl.

a Due to smaller size and high poalrising power of Li+ ion LiCl is more covalent than KCl. b Small cation Li+ ion highly polarizes large anion I- LiI is more covalent and hence has lower melting point. c Due to pseudo inert gas configuration Cu+ is more polarizing than Na+ and hence CuCl is more Covalent NaCl.

The crystal structure of sodium chloride, NaCl, a typical ionic compound. The purple spheres represent sodium cations, Na+, and the green spheres represent chloride anions, Cl−.

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.

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.

For example, the solubility of CaCl2 at room temperature is listed on Wikipedia as 64.7 g/ 100 g water, whereas the solubility of NaCl is listed as 35.72 g/ 100 g water. At room temperature, the density of a saturated solution of CaCl2 is 1.435 g/ml and the density of a saturated solution of NaCl is 1.199 g/ml.

For any compound to be soluble in water, It must satisfied the given below condition : Hydration energy of compound should be greater than its lattice energy. Hydration energy of potassium chloride is less than its lattice enthalpy so it is insoluble in water.

NaCl is an ionic compound. So it’s solubility is maximum in another ionic compound. So water is the only ionic compound in the given options, so B is the correct answer.

Like dissolves like. Since KCl is an ionic compound, it will be more soluble in polar solvents which have a high dielectric constant. The solubility of KCl is relatively more in CH3​OH(D=32), as both are polar molecules.

KCl – also known as sylvite – is freely soluble in water because of having electrolytic nature. In KCl, K stands for potassium and Cl stands for chlorine. Both of them when combined form the salt that is known as potassium chloride.

In which solvent is each of the following more likely to be soluble? KCl soluble in water. Explanation: KCl is a ionic compound ( K+ + Cl–), in the solid state of it electrostatic force of attraction strongly binds the K+ and Cl– together.

Like dissolves like. Since KBr is a polar ionic compound, it will be soluble in a polar solvent. The solvent with a higher value of dielectric constant will provide maximum solubility. It will be most soluble in polar solvents, i.e. with the highest value of D.
