Does salt affect the boiling point of water and why?
Salt will increase the boiling point and decrease the freezing point of water due to colligative properties. Table salt (NaCl) breaks into ions when dissolved. This lowers the vapor pressure of water. When salt dissolves its ions are moving around in the water, and some are near the surface. Rather than all the water just boiling off, some of these ions get in the way, which will raise the boiling point. This effect is not only caused by salt, but by dissolved substance. In general, the more ions or particles dissolved, the greater the effect on boiling point, so MgCl2 would have a greater effect on boiling point than NaCl, because MgCl2 dissociates into three ions instead of two.
What would the final boiling point of water be if 3 mol of NaCl were added to 1 kg of water (Kb 0.51 and degC(molkg) for water and i 2 for NaCl)?
103.06 degrees C
Why does an NaCl solution freeze at lower temperature than water but boils at higher temperature than water?
NaCl solution freezes at lower temp. than water but boils at higher temp.than water
How does the presence of dissolved sodium chloride affect the boiling and freezing point of water?
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
How much would the boiling point of water increase if 4 mol of NaCl were added to 1kg of water?
To determine the boiling point elevation of water when 4 mol of NaCl is added to 1 kg of water, we can use the formula: ΔT_b = i * K_b * m, where ΔT_b is the boiling point elevation, i is the van 't Hoff factor (which is 2 for NaCl), K_b for water is approximately 0.512 °C kg/mol, and m is the molality. Since NaCl dissociates into 2 ions (Na⁺ and Cl⁻), i = 2, resulting in a total of 8 mol of particles (4 mol NaCl × 2). The molality (m) is 4 mol / 1 kg = 4 mol/kg. Thus, ΔT_b = 2 * 0.512 °C kg/mol * 4 mol/kg = 4.096 °C. Therefore, the boiling point of water would increase by approximately 4.1 °C.
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.
What has a greater boiling point elevation when dissolved at a concentration of 1mol in water with NaCl or MgCl2?
In the same volume of water, one mole of MgCl2 will give rise to a greater boiling point elevation. This is explained by the fact that boiling point elevation is a colligative property, that is, the relative amounts of the constituents are important and not their identity. We can determine by inspection that, upon dissociation, more ions will be produced by MgCl2 than NaCl since there are more atoms in the MgCl2 molecule. So, for one mole of MgCl2, we will produce one mole of magnesium and two of chlorine (three total). For one mole of NaCl, we produce one mole each of potassium and chlorine. By employing the principle stated above, we can come to the correct conclusion.
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.
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.
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 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.
