Why does nacl have higher boiling point than KCl?

Nacl has higher lattice enthalpy as compared to kcl therefore it has higher melting point. The nuclear force of attraction is higher in nacl therefore the force required will be more in case of nacl as compared to kcl and thus nacl has hugher melting points.

Why is the melting point of nacl so high?

Sodium chloride has a high melting and boiling point There are strong electrostatic attractions between the positive and negative ions, and it takes a lot of heat energy to overcome them. Ionic substances all have high melting and boiling points.

Why KCl is more stable than NaCl?

Because potassium have ability to stabilize itself along with positive charge more than sodium. so KCl is more stable than NaCl. One more reason is that the atomic radius of potassium is greater than that of sodium so it can donate or lose its electron easily and becomes stable with positive charge.

Why does KCl have a higher melting point than i2?

b) KCl has a higher melting point than I2 The bonding in KCl is ionic, so KCl should have a high value for melting point. I2 is nonpolar, and the attractive forces between molecules are relatively weak dispersion forces, and so I2 should have a lower melting point.

Is KCl melting point high?

1,418°F (770°C)
Potassium chloride/Melting point

Why does NaCl have a higher melting point than LICL?

In short, NaCl has a very strong ionic bond due to the disparity in electronegativity (EN) between Na and Cl. This bond requires more energy to break resulting in a high melting point… According to that q1q2 is same for both. But ionic radius, Na+ < K+ , What has the most strongest ionic bond, yes, NaCl.

Why is melting point of NaCl higher than mgcl2?

Both sodium chloride and magnesium chloride are ionic solids. Also, magnesium is more electronegative as compared to sodium. These factors combine to result in a higher force of attraction in sodium chloride as compared to magnesium chloride and hence a higher melting point for the former.

Is KCl better than NaCl?

Nevertheless, in comparison with NaCl the saltiness of KCl is significantly lower when we compare the same mass concentrations. Despite all these objective disadvantages, KCl is still the best alternative for common salt (NaCl) substitution.

Why does NaCl have a higher melting point than Cl2?

NaCl forms a giant ionic lattice that requires high amounts of energy to break and therefore has a high melting point.
