43 Which of the following aqueous solutions has the greatest boiling point under typical conditions? (1) 1.0 M KC1(aq) is used (3) KCl(aq) 2.0 M KCl(aq) (2) CaC12(aq) solution (1.0 M) (4) vant 2.0 M CaC12(aq) 4 ant The Hoff factor with the highest BP has the greatest number of particlesions. CaCl2 combines to create 3 ==> Ca2+ and 2Cl- are electrolytes.
In a similar vein, individuals inquire as to which aqueous solution has the greatest boiling point.
Answer: (b) As we all know, the bigger the value of the van’t Hoff factor, the greater the rise in boiling point and, thus, the greater the boiling point of the solution will be. As a result, the boiling point of Na2St4 at 1.0 M is the greatest.
In addition, which solution has the lowest freezing point among the others?
When it comes to freezing point temperatures, the solution with the lowest freezing point temperature is the one with the greatest depression in freezing point ($$displaystyle Delta T f$$). The decrease in freezing point is a colligative feature that is dependent on the amount of solute particles present in the solution.
The boiling point and freezing point of a solution containing water and calcium chloride at Standard are shown in the following table.
1) The boiling point of a solution of water and calcium chloride at standard pressure will be higher than the normal boiling point of pure water, and 2) the freezing point of a solution of water and calcium chloride at standard pressure will be lower than the normal freezing point of pure water, thus providing the answer to the question
Which of the following watery solutions has the greatest osmotic pressure?
As a result, AlCl3 will impose the greatest osmotic pressure since its Van’t hoff factor is the largest.

Which solution has the greatest boiling point, according to this quiz?
In the presence of 0.75 m NaCl, the solution with the greatest boiling point is obtained.
Which of the following compounds has the greatest boiling point among the group of compounds?
n-Pentane is the compound with the highest boiling point of any known chemical. The boiling point of n-pentane is 36.1 degrees Celsius. The boiling point of isopentane is 27.8 degrees Celsius. The boiling point of neopentane is 9.5 degrees Celsius.
What causes salt to raise the boiling point?
Salt causes sodium chloride to break down into sodium and chlorine ions when it comes into contact with water. The water molecules need more energy in order to generate enough pressure to force the liquid molecules to exit the liquid’s border. The boiling point of water rises in direct proportion to the amount of salt (or any other solute) added.
How do you determine the solubility of a substance?
The solubility of a material refers to the quantity of the substance that can be dissolved in a solvent at a certain temperature under certain conditions. A saturated solution is one that has reached its maximum concentration. Calculate the solubility in grammes per 100 grammes of the compound by dividing the mass of the compound by the mass of the solvent and multiplying the result by 100 grammes.
What is the current state of the boiling point?
The relative strength of the four intermolecular interactions is as follows: ionic > hydrogen bonding > dipole dipole > Van der Waals dispersion forces (from strongest to weakest in order). The strength of each of these attractive forces will be determined by the number of functional groups that are present. The boiling point of a substance increases as the amount of carbons in the substance increases.
What is the most powerful intermolecular force known?
Hydrogen bonding is a kind of link formed between two atoms of hydrogen.
What are the elements that influence melting point?
There are intermolecular forces at work. A weak intermolecular force is defined as an attraction between molecules that is less powerful than the attraction between neighbouring molecules. Molecules have a certain shape. The melting of a material is also influenced by the shapes of molecules. Molecules are classified by their size. There are other considerations.
What role does pressure play in determining boiling point?
The Boiling Point is affected by pressure. Increases in atmospheric pressure result in a rise in boiling point, while drops in atmospheric pressure (as occurs as elevation increases) result in a reduction in boiling point. The pressure exerted on the water’s surface has the effect of keeping the water molecules confined.
Is there a reason why water has such a high boiling point?
No atom-to-atom connections are destroyed; only the bonds between water molecules, in this instance hydrogen bonding, are disrupted in this process. As one of the most potent intermolecular interactions known to science, hydrogen bonding is responsible for the high boiling point of water.
Can you tell me what happens to the boiling point of water when ethylene glycol is added?
In fact, when you go one step further and make a 30/70 combination of water and ethylene glycol, the boiling point increases to 235 degrees Fahrenheit (113 degrees Celsius) while the freezing point drops to minus 67 degrees Fahrenheit (minus 55 degrees Celsius).
