Why does NaCl have higher boiling point than water?
When you add salt to water, sodium chloride dissociates into sodium and chlorine ions. The water molecules need more energy to produce enough pressure to escape the boundary of the liquid. The more salt (or any solute) added to water, the more you raise the boiling point.
How does the boiling point of a solution of salt water compare to the boiling point of pure water?
The boiling point elevation is the amount the boiling point temperature increases compared to the original solvent. For example, the boiling point of pure water at 1.0atm is 100oC while the boiling point of a 2\% salt-water solution is about 102oC.
Why is NaCl melting point higher than h2o?
Explanation: (i) Its high melting point is due to the ionic bonds it has between the ions of opposite charge. (ii) Its ions solvate ( Na+ , Cl− ) in water solution and is thus a strong electrolyte in water.
Why does NaCl have a higher melting point than mgcl2?
This is because the bonds that exist between sodium and chloride, and magnesium and chloride are not entirely ionic and some degree of covalency exists. 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 the boiling point of salt water higher or lower than the boiling point of pure water explain?
Non-Volatile Solutes there are fewer water molecules in the vapor (i.e., lower vapor pressure) above the NaCl solution than in the vapor above pure water, and. the boiling point of the NaCl solution will be greater than the boiling point of pure water.
Why is NaCl melting point so high?
Sodium Chloride has a high melting point, as it has a giant ionic lattice hence has strong electrostatic forces of attraction between oppositely charged ions, which requires lots of energy to overcome the forces.
Why does NaCl have a really high melting point?
Why does NaCl have a fairly high melting point?
Sodium chloride has a high melting point because the lattice is constructed from positive sodium ions and negative chloride ions. This ions attract each other with a strong electrostatic force. This leads to a strong construction. To break the bonds between the ions you jeed high temperature.
