Which of the solutions has the highest boiling point?
The solution with the highest boiling point is 0.75 m NaCl. Which of the following compound has the highest boiling point? The compound having the highest boiling point is n- pentane. of n-pentane is 36.1 degrees celsius. of isopentane is 27.8 degrees celsius. of neopentane is 9.5 degrees celsius.
Which aqueous solution has the highest osmotic pressure?
Which aqueous solution has the highest osmotic pressure? So AlCl3 will exert highest osmotic pressure as its Van't hoff factor is maximum.
What factors affect the boiling point of aqueous solutions?
That means that the increase in the boling point will be related to the number of particles (molecules or ions) present in the solution. The higher the number of particles (molecules or ions) the higher the increase in the boiling point. All the aqueous solutions presented are electrolytes, i.e. the solutes are ionic compounds.
What determines the boiling point of a substance?
The temperature at which a liquid's vapor pressure matches the pressure surrounding the liquid is known as the boiling point of that substance. To determine the higher boiling point of any compound or elements, we have to see three factors:
Which aqueous solution has highest boiling point?
Thus, Na3PO4 has the highest boiling point.
Which of the following aqueous solutions has the highest boiling point quizlet?
NaCl has the greatest product, so it will have the largest T and the highest boiling point. Colligative properties are those that depend on the number of particles dissolved in a solvent. The more particles in the solvent, the greater the effect the solute has on the properties of the solution.
Which of the following aqueous solutions would have the highest boiling point NaNO3 HF C6H12O6 CaCl2?
Which of the following aqueous solutions would have the highest boiling point? NaNO3 would dissociate into Na^+ and NO3^-, HF does dissociate, but CaCl2 dissociates into Ca^2+ and 2Cl, which has more ions inside and therefore a higher boiling point.
Which of the following 1.0 molal aqueous solutions would have the highest boiling point?
Thus, Na3PO4 has the highest boiling point.
Which compound will exert the highest osmotic pressure?
So AlCl3 will exert highest osmotic pressure as its Van't hoff factor is maximum.
Is the boiling point of calcium chloride higher than the boiling point of pure water?
The answer to the question is that 1) the boling 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.
