Will elevation in boiling point be same for 0.5 m NaCl and 0.5 M sucrose solution explain?

Answer: no as boiling point is a colligative property. Explanation: here the vant hoff’s of sucrose is 1 and NaCl is 2 so elevation in boiling point will be different.

Which of the following has higher boiling point and why 0.1 m NaCl or 0.1 M glucose?

The boiling point depends only on the Van’t Hoff factor. That means higher the Van’t Hoff factor, higher will be the boiling point and vice-versa. Hence, 0.1 M of NaCl has the higher boiling point.

Which has higher boiling point NaCl or CaCl2?

From above two expressions we easily conclude that 1M solution of CaCl2 has higher boiling point than 1M solution of NaCl.

What is the molal boiling-point elevation constant for NaCl?

The increase in the boiling point of a 1.00 m aqueous NaCl solution will be approximately twice as large as that of the glucose or sucrose solution because 1 mol of NaCl produces 2 mol of dissolved ions. Hence a 1.00 m NaCl solution will have a boiling point of about 101.02°C.

Which of the following has higher boiling point and why 0.1 m NaCl or 0.1 M glucose II explain Henry’s Law for the dissolution of gas in a liquid?

0.1 molal solution of sodium chloride will have higher ΔTb and higher boiling point as well because it dissociates into ions. At the sametime, 0.1 molal glucose solution being a molecular solid will not dissociate into ions.

Will the elevation in boiling point be the same for 1’m NaCl 1m glucose Why?

No, the elevation in boiling point is not the same. Elevation in boiling point is a colligative property which depends on the number of particles. NaCl is an ionic compound which dissociates in solution to give more number of particles whereas sugar is made up of molecules and thus does not dissociate.

Which will have 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 will be the boiling point of 0.1 M glucose solution?

100.16∘ C
molal aqueous solution of glucose boils at 100.16∘ C.

Why does cacl2 have a higher melting point than NaCl?

Calcium chloride is more effective at melting ice because it can break down into three ions instead of two: one calcium ion and two chloride ions. While some other compounds that can melt ice and snow don’t include chloride, they are much more expensive than sodium chloride or calcium chloride.

What is the boiling point of NaCl?

2,669°F (1,465°C)
Sodium chloride/Boiling point

How do you find the boiling point elevation?

1. Solution. To find the temperature change elevation of a solvent by a solute, use the equation: ΔT = iKbm.
2. Calculate the Molality of the NaCl. molality (m) of NaCl = moles of NaCl/kg water. From the periodic table:
3. Find ΔT. ΔT = iKbm.
4. Answer. Adding 31.65 g of NaCl to 220.0 mL of water will raise the boiling point by 2.53 °C.

How do you find boiling point elevation?

Boiling-Point Elevation Example

1. Glucose is our solute and water is the solvent.
2. Kb for water is 0.51 degrees Celsius kg/mol.
3. The molar mass of glucose is 180 g/mol.
4. The boiling point of water is 100 degrees Celsius.
5. The equation for boiling-point elevation is delta T = mKb.

How much NaCl does it take to raise boiling point?

Adding 31.65 g of NaCl to 220.0 mL of water will raise the boiling point 2.53 °C. Boiling point elevation is a colligative property of matter. That is, it depends on the number of particles in a solution and not their chemical identity.

What is the boiling point of sucrose in water?

The greater the concentration of solute in the solution, the greater the boiling point elevation. A graph detailing the elevation in the boiling point of water upon the addition of sucrose is provided above. At 1atm of pressure, pure water boils at 100 o C. However, a 10 molal solution of sucrose in water boils at approximately 105 o C.

What is the relationship between molal concentration and boiling point elevation?

It has been shown experimentally that the elevation in boiling point is directly proportional to the molal concentration of the solute in a solution. Where, kb is the boiling point elevation constant or the ebullioscopic constant and m is the molarity of the solution that is equal to the number of moles of solute dissolved in 1 kg of solvent.

Can the boiling point of sugar and sodium chloride be different?

Answer The elevation in boiling point be different if 0.1 mole of sodium chloride or 0.1 mole of sugar is dissolved in 1 L of water. Sugar is non electrolyte and it do not dissociate in aqueous solution. N aC l is a strong electrolyte and completely dissociates to give sodium ions and chloride ions.
