Nacl is a salt and forms ions in the solution Na+ Cl- , in other words it has 2 molecules dissociated. On the other hand Sucrose does not dissociate it stays as one mole of sugar. This is why the boiling point of Nacl is higher then Sucrose.

Sodium Chloride is an ionic solid. Ethanol C2H6O, Carbon tetrachloride, CCl4 andphosphorus oxychloride, POCl3 are all liquids with covalently bonded molecules. In these liquids there are some attractive forces between the molecules otherwise they would be gases.

To boil the solid you have to put in sufficient energy to break down the lattice structure, and if this forms a liquid then further energy is required to vaporise it.

The energy to break down the NaCl ionic lattice is much greater than that required to vaporise the liquids.

Because salt water has a slightly higher boiling point, it tends to boil not as fast as fresh water does.

What has a higher boiling point NaCl or Cl2?

NaCl is an ionic solid with a high boiling point. Cl2 is held together by weak dispersion forces and is a gas at room temperature. That means Cl2 has already boiled and formed a gas at a temperature lower than room temperature.


What is the effect of NaCl and CaCl2 on the boiling point of water?

The water with solved ions has greater boiling point. The dissolved salts increase the boiling point of water.


What mass of NaCl would have to be dissolved in 1.000 kg of water to raise the boiling point by 2.00 degrees Celsius?

114.14g NaCl


Which will have the lowest boiling point pure water 0.5 M NaCl aq 1.0 M NaCl aq or 2.0 M NaCl aq?

Pure Water


Why does a 0.10 molality solution of NaCl have a higher boiling point and a lower freezing point than a 0.10 molality solution of C6H12O6?

The higher the molality the higher the boiling point and the lower the freezing point. Conversely, the lower the molality the lower the boiling point and the lower the freezing point. Now let's analyze the problem: The total molality of 0.10 m of NaCl is 0.20 m. This is based on the property of the ionic bond. Ionic bonds are salts and thus strong electrolytes, which means they break up into all of there constituents in solution. Since two substances make up sodium chloride (sodium and chlorine), that means you'll have two substances overall. Your total molality was .10, and you have two substances, which means you're left with 0.10 * 2 = 0.20 m. Glucose is made of covalent bonds which do NOT break up in solution. This means you are left with one substance, C6H12O6. So you have 0.10 * 1 = 0.10. You are left comparing 0.20m of NaCL and 0.10m of C6H12O6. The higher molality has the higher boiling point.

Which has the higher boiling point NaCl or HCl and why?

Sodium chloride has a higher boiling point because is a salt with ionic bonds.


Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?

No, if both substances are dissolved in water, because sodium chloride spontaneously dissociates into two ions that act independently in raising the boiling point, while dissolved sucrose does not dissociate into entities smaller than molecules. Therefore, 0.1 m NaCl will raise the boiling point about twice as much as 0.1 m sucrose.

What is the effect of impurities on boiling point of different chemicals?

It varies. A saturated solution of NaCl in water increases the boiling point, higher than 100oC. I suppose most impurities increase the boiling point.


What has a higher boiling point Hg NaCl or He?

He, Helium has a boiling point of -269°C (4.2 Kelvins) and it is a noble gas also. Hg, Mercury, is a liquid at room temperature. It boils at +356.73°C (629.88K). NaCl is "table salt", which is a solid. You can liquify salt, and even boil it, at a high enough temperature. Its boiling point is +1,413°C (1,686K). So NaCl has the highest boiling point.
