Why does the KCl solution have the higher boiling point?

KCl is an ionic compound and glucose is a molecular compound. Ionic compounds have higher boiling points than molecular compounds. Therefore, KCl will have the higher boiling point.

What is the boiling point of KCl solution?

2,588°F (1,420°C)
Potassium chloride/Boiling point

Will the elevation in boiling point temperature be the same for 0.1 m nacl and 0.1 M sucrose solution explain?

Will elevation in boiling point temperature be same for 0.1M NaCI and 0.1M sucrose solution? no, it will not be the same because collingative property does not depend upon molar concentration alone but also upon the number of particles (ions) in solution.

Why does 0.1 M KCl have a higher boiling point?

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

Which has the lowest boiling point at 1 atm pressure 0.1 M KCl 0.1 M urea 0.1 m cacl2 0.1 m alcl3?

The correct answer will be option b. So, as the concentration of all the three compounds are the same ,the boiling point will be compared by using the van’t hoff factor. So the lowest van’t hoff factor is of urea and therefore it will have the lowest boiling point.

Why does the boiling point of 1M KCl?

KCl can dissociate in water and is an electrolyte. So, 1 molecule of KCL gives 2 ions. Hence, its van’t Hoff factor is 2. So, the elevation of boiling point of 1M KCl solution will be nearly double than that of 1M sugar solution.

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.

Will the elevation in boiling point be same if 0.1 mole of sodium chloride or 0.1 mole of sugar is dissolved in one Litre of water?

Hence, elevation in boiling point in both the cases is not the same. Elevation in boiling point in case of dissolving 0.1 mol of sodium chloride in 1 L of water will be higher as compared to that of 0.1 mol of sugar.

Which one will have higher boiling point 0.1 M sucrose or 0.1 M KCl?

0.1 m KCI will have higher boiling point. This is because KCl dissociates in water to give two ions (KCI→k4+Cl-), whereas glucose does not dissociate.

Which has higher boiling point 0.1 M KCl or 0.1 M glucose?

The number of constituent ions produced by KCl is more than that is produced by glucose. Thus, the boiling point of 0.1 molal aqueous solution of KCl is more than 0.1 molal of glucose.
