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 will have the lowest boiling point because it does not contain any solute particles to elevate the boiling point. As the concentration of NaCl increases, the boiling point also increases due to an increase in the number of solute particles that disrupt the formation of water vapor. Therefore, 0.5 M NaCl will have a higher boiling point than pure water, followed by 1.0 M NaCl, and finally 2.0 M NaCl will have the highest boiling point.
What is the effect of NaCl and CaCl2 on the boiling point of water?
Adding NaCl (table salt) or CaCl2 (calcium chloride) to water raises the boiling point of water. This is due to the phenomenon of boiling point elevation, where the presence of solute particles in water disrupts its ability to form vapor, requiring higher temperatures to boil.
Which has higher boiling point Urea or Sodium chloride?
Sodium chloride (NaCl) has a higher boiling point than urea. This is because sodium chloride forms ionic bonds which are stronger than the hydrogen bonds in urea. Stronger bonds require more energy to break, resulting in a higher boiling point.
Which has a higher boiling point between NaCl and MgCl2?
MgCl2 because it has more electrons (due to the Mg over Na). Because of the higher number of electrons, it has higher dispersion forces (attractive forces). This means that more energy (heat) is required to unstick the molecules into a different state of matter.NaCl, due to complex arrangement and interaction of molecules, can't be easily explained by using simple dispersion, dipole-dipole interaction.Although NaCl's higher melting point can be explained by its bonding in its crystal lattice arrangement compare to MgCl2.
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.
Will elevation in boiling point be same for 0.1 m NaCl and 0.1m sucrose solution?
No, the elevation in boiling point will not be the same for a 0.1 m NaCl solution and a 0.1 m sucrose solution. This is because the elevation in boiling point is directly proportional to the number of particles in the solution, known as the van't Hoff factor. NaCl dissociates into two ions (Na+ and Cl-) in solution, so it has a van't Hoff factor of 2, while sucrose does not dissociate and has a van't Hoff factor of 1. Therefore, the NaCl solution will have a greater elevation in boiling point compared to the sucrose solution.
Which has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a 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.

Boiling point in NaCl and KCl?
The boiling point of NaCl is 1 413 0C. The boiling point of potassium chloride is 1 420 0C.
What is NaCl boling point?
The boiling point of NaCl is 1413 oC.
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.
What is sodium chloride boiling and melting point?
Melting point of NaCl: 801 0C Boiling point of NaCl: 1 413 0C.
Which would have a lower boiling point NaCl or SCl2?
The boiling point of sodium chloride (NaCl) is 801 oC.Sulfur dichloride (SCl2) is decomposed before boiling.
What is a boiling point of NaCl?
The boiling point of sodium chloride is 1 413 0C.
