1, the molal boiling point elevation constant for water is 0.51°C/m. Thus a 1.00 m aqueous solution of a nonvolatile molecular solute such as glucose or sucrose will have an increase in boiling point of 0.51°C, to give a boiling point of 100.51°C at 1.00 atm.1, the molal boiling point elevationboiling point elevationBoiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent.https://en.wikipedia.org › wiki › Boiling-point_elevation

Answer : 0.1 M of NaCl has the higher boiling point.

Which of the following has highest boiling point 0.1 M glucose?

The right answer is b) 0.1 BaCl2 has the highest boiling point.

Why KCl has higher boiling point than glucose?

This is because KCl dissociates in water to give two ions (KCI→k4+Cl-), whereas glucose does not dissociate. Therefore, number of solute particles is greater in 0.1 m KCl as compared to 0.1 m glucose. Hence, elevation in boiling points in 0.1 m KCl will be higher and therefore, its boiling point will be higher.

What has the highest boiling point?

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

Which has low boiling point?

Which will have a higher boiling point 0.1 m NaCl or 0.1 m bacl2 solution in water?

Since both the salt solution have same concentration, therefore the salt which gives maximum number of ions will show higher boiling point. NaCl dissociate to give two ions while BaCl. Hence BaCl2 posses high boiling point.

What is the boiling point of 0.1 m na2so4?

Boiling Point/Range 100°C. Partition Coefficient N/A. (log POW). Flash Point: N/A.

Which has maximum boiling point 0.1 N NaCl?

0.1 M aqueous solution of ferric chloride has the highest boiling point. The dissociation of one molecule of ferric chloride gives the maximum number of ions (four ions) in the solution. Glucose is a non-electrolyte and it does not undergo dissociation.

Which one has highest boiling point 0.1 N Na2SO4?

Among the given alternatives, Na2SO4 will exhibit the highest boiling point since it will dissociate into 3 ions when dissolved in the solution.

What is the boiling point of glucose?

Predicted data is generated using the ACD/Labs Percepta Platform – PhysChem Module Density: 1.6±0.1 g/cm 3 Boiling Point: 527.1±50.0 °C at 760 mmHg Vapour Pressure: 0.0±3.1 mmHg at 25°C Enthalpy of Vaporization: 92.2±6.0 kJ/mol Flash Point: 286.7±26.6 °C.

Which one has the highest melting point?

The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon.

Which has higher boiling point 0.1 m NaCl or 0.1 m CaCl2?

0.1 M CaCl_(2) has higher boiling point than 0.1 M NaCl. 0.1 M glucose exerts higher osmotic pressure than 0.08 M CH_(3)COOH (25% dissociated).

Which has maximum boiling point at one atmospheric pressure?

Van’t hoff is the number of ions a compound dissociates. So here we can see that the highest value of van’t hoff factor is of BaCl2 so it will have highest value of elevation constant and in continuation will have the highest boiling point among all. So, the correct answer is Option C.

Which has higher boiling point NaCl or cacl2?

So from everything I’ve learned, NaCl would be more effective for the melting, because calcium chloride dissociates into three ions and sodium chloride dissociates into two, so that would make the boiling point of water with calcium chloride higher.

Which solution has lowest freezing point?

Remember, the greater the concentration of particles, the lower the freezing point will be. 0.1mCaI2 will have the lowest freezing point, followed by 0.1mNaCl, and the highest of the three solutions will be 0.1mC6H12O6, but all three of them will have a lower freezing point than pure water.

Which is not a Colligative property?

Both solutions have the same freezing point, boiling point, vapor pressure, and osmotic pressure because those colligative properties of a solution only depend on the number of dissolved particles. Other non-colligative properties include viscosity, surface tension, and solubility.

What increases boiling point?

Compounds that can hydrogen bond will have higher boiling points than compounds that can only interact through London dispersion forces. An additional consideration for boiling points involves the vapor pressure and volatility of the compound. Typically, the more volatile a compound is, the lower its boiling point.

Do alkynes have higher boiling points?

Alkynes have higher boiling points than alkanes or alkenes, because the electric field of an alkyne, with its increased number of weakly held π electrons, is more easily distorted, producing stronger attractive forces between molecules.

Which order of boiling point is correct?

The decreasing order of boiling points (highest to lowest) are as follows: (III) > (I) > (II) alcohol > ether > alkane. “NF ”mar fil Therefore, it has the highest boiling point. Key Terms. Compound B does not form hydrogen bond.

Which solution has lowest boiling point?

since C6H12O6 is having the highest value of Vont Hoff factor, $$i$ $; and i is directly proportional to the depression in freezing point hence, C6H12O6 is having the lowest boiling point.

Which one has the lowest boiling point * 1 point?

Thus, option A is the correct answer, i.e. CH3Cl has the lowest boiling point. Note:Like boiling point melting point of a solid also varies depending on the same factors. Under intermolecular forces, the forces caused by hydrogen bonding are the strongest and lead to the higher boiling point among the molecules.
